1.Spring 基础

2.Spring 常用配置

3.Spring 高级话题

4.Spring mvc基础

5.Spring Boot基础

5.1 Spring boot概述

5.1.1 什么是spring boot

使用习惯优于配置的理念.不用或者只需要很少的spring配置.

5.1.2 Spring boot核心功能

• 1.独立运行的Spring 项目
  支持用jar包的形式运行.
• 2.内嵌Servlet容器
  内嵌Tomcat,jetty
• 3.提供starter,简化maven配置.
• 4.自动配置Spring
• 5.准生产的应用监控
  http,ssh,telnet对运行时的项目进行监控
• 6.无代码生产和XML配置

5.1.3 Spring boot优缺点

优点
- 1)快速构建项目
- 2)对主流开发框架的无配置集成
- 3)项目可以独立运行,无须外部依赖servlet容器
- 4)提供运行时的应用监控
- 5)机极大的提高了开发,部署效率
- 6)与云计算的天然集成.
缺点
- 1)书籍文档少
- 2)不认可spring,可能不习惯

5.1.4 关于本书Spring boot版本

Spring boot 1.3.0

5.2 Spring boot快速搭建

5.2.1 http://start.spring.io

进入该页面能协助创建spring boot项目.

5.2.2 Spring Tool Suite

工具不错.

5.2.3 Intellij IDEA

工具口碑好

5.2.4 Spring boot CLI

下载链接
查看10.2章节.

5.2.5 maven 手工构建

5.2.6 简单演示

@SpringBootApplication :开启自动配置.
通过maven命令: mvn spring-boot:run

6.Spring Boot核心

6.1 基本配置

6.1.1 入口类和@SpringBootApplicaion

@Target(ElementType.TYPE)@Retention(RetentionPolicy.RUNTIME)@Documented@Inherited@Configuration@EnableAutoConfiguration@ComponentScanpublic @interface SpringBootApplication {}

@EnableAutoConfiguration让Spring boot根据类路径中的jar包依赖为当前项目进行自动配置.
Spring Boot启动类要放在groupId+arctifactID目录下.

@EnableAutoConfiguration详解

6.1.2 关闭特定的自动配置

@SpringBootApplication(exclude={DateSourceAutoConfiguration.class})

6.1.3 定制Banner

1) 修改banner内容

/src/main/resources目录下创建一个banner.txt文件，然后将ASCII字符画复制进去，就能替换默认的banner了.

字符画生成地址

2)属性设置.

属性 说明 ${AnsiColor.BRIGHT_RED} 设置控制台中输出内容的颜色 ${application.version} 用来获取MANIFEST.MF文件中的版本号 ${spring-boot.version} Spring Boot的版本号

application.formatted−version|格式化后的{application.version}版本信息

3)关闭banner方法1

    SpringApplication application = new SpringApplication(App.class);    /*     * Banner.Mode.OFF:关闭;     * Banner.Mode.CONSOLE:控制台输出，默认方式;     * Banner.Mode.LOG:日志输出方式;     */     application.setBannerMode(Banner.Mode.OFF);      application.run(args); 

4)关闭banner方法2

在application.proerpties进行banner的显示和关闭：

是否显示banner，可选值[true|false]

spring.main.show-banner=false

spring boot banner

6.1.4 Spring Boot的配置文件

application.properties或application.yml

//举几个例子:server.port=9090server.context-path=/hellobootserver: port: 9090 contextPath:/hellobootspring.redis.cluster.nodes[0]=192.168.0.1:6379  spring.redis.cluster.nodes[1]=192.168.0.2:6379  spring:     redis:        cluster:           nodes:              - 192.168.0.1:6379              - 192.168.0.2:6379  

Spring Boot application.properties或application.yml相关配置

application.properties 改成 application.yml

6.1.5 Start pom

启动日志附件

6.5.1 运行原理

6.1.1 中的
@SpringBootApplication中有一个核心注解为@EnableAutoConfiguration

@Target(ElementType.TYPE)@Retention(RetentionPolicy.RUNTIME)@Documented@Inherited@AutoConfigurationPackage@Import(EnableAutoConfigurationImportSelector.class)public @interface EnableAutoConfiguration {    /**     * Exclude specific auto-configuration classes such that they will never be applied.     * @return the classes to exclude     */    Class<?>[] exclude() default {};    /**     * Exclude specific auto-configuration class names such that they will never be     * applied.     * @return the class names to exclude     * @since 1.3.0     */    String[] excludeName() default {};}

而EnableAutoConfiguration的关键功能为@Import注解导入EnableAutoConfigurationImportSelector的配置功能,EnableAutoConfigurationImportSelector使用SpringFactoriesLoader.loadFactoryNames方法来扫描META-INF/spring.factories文件中的jar包,而spring-boot-autoconfigure-1.3.0.x.jar中就有spring.factories.

//摘取核心代码package org.springframework.core.io.supportpublic abstract class SpringFactoriesLoader {public static final String FACTORIES_RESOURCE_LOCATION = "META-INF/spring.factories";public static List<String> loadFactoryNames(Class<?> factoryClass, ClassLoader classLoader) {        String factoryClassName = factoryClass.getName();        try {            Enumeration<URL> urls = (classLoader != null ? classLoader.getResources(FACTORIES_RESOURCE_LOCATION) :                    ClassLoader.getSystemResources(FACTORIES_RESOURCE_LOCATION));            List<String> result = new ArrayList<String>();            while (urls.hasMoreElements()) {                URL url = urls.nextElement();                Properties properties = PropertiesLoaderUtils.loadProperties(new UrlResource(url));                String factoryClassNames = properties.getProperty(factoryClassName);                result.addAll(Arrays.asList(StringUtils.commaDelimitedListToStringArray(factoryClassNames)));            }            return result;        }        catch (IOException ex) {            throw new IllegalArgumentException("Unable to load [" + factoryClass.getName() +                    "] factories from location [" + FACTORIES_RESOURCE_LOCATION + "]", ex);        }    }    }

6.5.2 核心注解

打开spring.factories中的任意一个AutoConfiguration文件,一般都有下面的条件注解,在spring-boot-autoconfigure-1.3.0.x.jar的org.springframework.boot.autoconfigure.condition包下,条件注解如下.

名称 说明 备注 @ConditionalOnBean 当容器里存在指定的Bean的条件下 @ConditionalOnClass 当前类路径下存在指定的类的条件下 @ConditionalOnExpression 基于SpEL表达式作为判断条件 @ConditionalOnJava 基于JVM版本作为判断条件 @ConditionalOnJndi 在JNDI存在的条件下查找指定的位置 @ConditionalOnMissingBean 当容器里没有指定的Bean的条件下 @ConditionalOnMissingClass ConditionalOnMissingClass @ConditionalOnNotWebApplication 当前项目不是web项目的条件下 @ConditionalOnProperty 指定的属性是否有指定的值的条件下 @ConditionalOnResource 类路径下是否有指定的值 @ConditionalOnSingleCandidate 指定Bean在容器中只有一个，或者虽然有多个但是指定首选的Bean @ConditionalOnWebApplication 当前项目是Web项目的条件下

ConditionalOnWebApplication 源码如下:

@Target({ ElementType.TYPE, ElementType.METHOD })@Retention(RetentionPolicy.RUNTIME)@Documented@Conditional(OnWebApplicationCondition.class)public @interface ConditionalOnWebApplication {}

其中@Conditional是OnWebApplicationCondition.class
OnWebApplicationCondition源码如下

@Order(Ordered.HIGHEST_PRECEDENCE + 20)class OnWebApplicationCondition extends SpringBootCondition {    private static final String WEB_CONTEXT_CLASS = "org.springframework.web.context."            + "support.GenericWebApplicationContext";    @Override    public ConditionOutcome getMatchOutcome(ConditionContext context,            AnnotatedTypeMetadata metadata) {        boolean webApplicationRequired = metadata                .isAnnotated(ConditionalOnWebApplication.class.getName());        ConditionOutcome webApplication = isWebApplication(context, metadata);        if (webApplicationRequired && !webApplication.isMatch()) {            return ConditionOutcome.noMatch(webApplication.getMessage());        }        if (!webApplicationRequired && webApplication.isMatch()) {            return ConditionOutcome.noMatch(webApplication.getMessage());        }        return ConditionOutcome.match(webApplication.getMessage());    }    private ConditionOutcome isWebApplication(ConditionContext context,            AnnotatedTypeMetadata metadata) {        if (!ClassUtils.isPresent(WEB_CONTEXT_CLASS, context.getClassLoader())) {            return ConditionOutcome.noMatch("web application classes not found");        }        if (context.getBeanFactory() != null) {            String[] scopes = context.getBeanFactory().getRegisteredScopeNames();            if (ObjectUtils.containsElement(scopes, "session")) {                return ConditionOutcome.match("found web application 'session' scope");            }        }        if (context.getEnvironment() instanceof StandardServletEnvironment) {            return ConditionOutcome                    .match("found web application StandardServletEnvironment");        }        if (context.getResourceLoader() instanceof WebApplicationContext) {            return ConditionOutcome.match("found web application WebApplicationContext");        }        return ConditionOutcome.noMatch("not a web application");    }}

有方法isWebApplication和getMatchOutcome.
isWebApplication是判断是否为webApplication.
getMatchOutcome 实现是abstract class SpringBootCondition的getMatchOutcome.
matches是实现了接口Condition的boolean matches,
SpringBootCondition中matches有调用了自身的getMatchOutcome方法.
捋捋核心原理1-关于Condition:
1.顶级接口 public interface Condition,方法matches
2.抽象类 abstract class SpringBootCondition,实现matches,同时调用自己的抽象方法 getMatchOutcome
3.具体类 class OnWebApplicationCondition extends SpringBootCondition,继承的同时重写getMatchOutcome,里面有判断.最终实现了被顶级接口matches是实现了接口Condition的boolean的matches判断现象..

class OnWebApplicationCondition extends SpringBootCondition{}//摘选部分代码public abstract class SpringBootCondition implements Condition {    @Override    public final boolean matches(ConditionContext context,            AnnotatedTypeMetadata metadata) {        String classOrMethodName = getClassOrMethodName(metadata);        try {            ConditionOutcome outcome = getMatchOutcome(context, metadata);            logOutcome(classOrMethodName, outcome);            recordEvaluation(context, classOrMethodName, outcome);            return outcome.isMatch();        }        catch (NoClassDefFoundError ex) {            throw new IllegalStateException("Could not evaluate condition on "                    + classOrMethodName + " due to internal class not found. "                    + "This can happen if you are @ComponentScanning a "                    + "springframework package (e.g. if you put a @ComponentScan "                    + "in the default package by mistake)", ex);        }        catch (RuntimeException ex) {            throw new IllegalStateException(                    "Error processing condition on " + getName(metadata), ex);        }    }    public abstract ConditionOutcome getMatchOutcome(ConditionContext context,            AnnotatedTypeMetadata metadata);}public interface Condition {    /**     * Determine if the condition matches.     * @param context the condition context     * @param metadata metadata of the {@link org.springframework.core.type.AnnotationMetadata class}     * or {@link org.springframework.core.type.MethodMetadata method} being checked.     * @return {@code true} if the condition matches and the component can be registered     * or {@code false} to veto registration.     */    boolean matches(ConditionContext context, AnnotatedTypeMetadata metadata);}

6.5.3 实例分析

分析一个简单的SpringBoot内置的自动配置功能:http编码配置.

@ConfigurationProperties(prefix = "spring.http.encoding")//application.properties和配置的前缀是spring.http.encoding public class HttpEncodingProperties {    //默认配置UTF-8,如果要修改用配置 spring.http.encoding.Charset=GBK    public static final Charset DEFAULT_CHARSET = Charset.forName("UTF-8"); //默认配置是UTF-8    /**     * Charset of HTTP requests and responses. Added to the "Content-Type" header if not     * set explicitly.     */    private Charset charset = DEFAULT_CHARSET;    /**     * Force the encoding to the configured charset on HTTP requests and responses.     */     //设置forceEncoding 默认true,如果要修改用配置 spring.http.encoding.force=false    private boolean force = true;    public Charset getCharset() {        return this.charset;    }    public void setCharset(Charset charset) {        this.charset = charset;    }    public boolean isForce() {        return this.force;    }    public void setForce(boolean force) {        this.force = force;    }}@Configuration@EnableConfigurationProperties(HttpEncodingProperties.class)//对上面配置类HttpEncodingProperties.开启属性注入,通过EnableConfigurationProperties,使用@Autowired注入.@ConditionalOnClass(CharacterEncodingFilter.class)//当CharacterEncodingFilter在类路径的条件下//当设置spring.http.encoding=enabled的情况下,如果么有设置则默认true.@ConditionalOnProperty(prefix = "spring.http.encoding", value = "enabled", matchIfMissing = true)public class HttpEncodingAutoConfiguration {    @Autowired    private HttpEncodingProperties httpEncodingProperties;    @Bean//使用java配置的方式配置CharacterEncodingFilter这Bean    @ConditionalOnMissingBean(CharacterEncodingFilter.class)//当容器中没有的时候则新建这个Bean    public CharacterEncodingFilter characterEncodingFilter() {        CharacterEncodingFilter filter = new OrderedCharacterEncodingFilter();        filter.setEncoding(this.httpEncodingProperties.getCharset().name());        filter.setForceEncoding(this.httpEncodingProperties.isForce());        return filter;    }}

捋捋核心原理2-自动配置
有配置参数属性Bean-HttpEncodingProperties.java,有使用的配置前缀名称及配置属性名称
然后有一个配置Bean-HttpEncodingAutoConfiguration.java,这个里面用到了配置参数属性类,但是里面会用到捋捋核心原理1中的各种Condition.
核心原理总理解:
@SpringBootApplication–核心注解–>@EnableAutoConfiguration—->@Import(EnableAutoConfigurationImportSelector.class)–使用–>
SpringFactoriesLoader.loadFactoryNames–方法来扫描–>META-INF/spring.factories(spring-boot-autoconfigure-1.3.0.x.jar中,记录有哪些自动配置)–关于配置,举例HttpEncoding–>参数配置HttpEncodingProperties,自动配置HttpEncodingAutoConfiguration(spring..factories有记录,被loadFactoryNames扫走)—->HttpEncodingAutoConfiguration用Condition来判断参数配置值来启用符合条件的功能.

还有一点注意理解 想查看某个自动配置有哪些配置属性,到其对应的Properties.java累中查看即可!!
比如说spring-boot-autoconfigure-1.3.0.RELEASE解压后META-INF目录下有spring.factories,里面有Redis相关的自动配置类:springorg.springframework.boot.autoconfigure.data.redis.RedisAutoConfiguration.打开该源码

//节选源码@Configuration@ConditionalOnClass({ JedisConnection.class, RedisOperations.class, Jedis.class })@EnableConfigurationPropertiespublic class RedisAutoConfiguration {    @Bean(name = "org.springframework.autoconfigure.redis.RedisProperties")    @ConditionalOnMissingBean    public RedisProperties redisProperties() {        return new RedisProperties();    }

里面提到:RedisProperties,查看就知道配置有database,host,password,port,timeout,pool等

package org.springframework.boot.autoconfigure.data.redis;import org.springframework.boot.context.properties.ConfigurationProperties;@ConfigurationProperties(prefix = "spring.redis")public class RedisProperties {    /**     * Database index used by the connection factory.     */    private int database = 0;    /**     * Redis server host.     */    private String host = "localhost";    /**     * Login password of the redis server.     */    private String password;    /**     * Redis server port.     */    private int port = 6379;    /**     * Connection timeout in milliseconds.     */    private int timeout;    private Pool pool;    private Sentinel sentinel;    public int getDatabase() {        return this.database;    }    public void setDatabase(int database) {        this.database = database;    }    public String getHost() {        return this.host;    }    public void setHost(String host) {        this.host = host;    }    public String getPassword() {        return this.password;    }    public void setPassword(String password) {        this.password = password;    }    public int getPort() {        return this.port;    }    public void setPort(int port) {        this.port = port;    }    public void setTimeout(int timeout) {        this.timeout = timeout;    }    public int getTimeout() {        return this.timeout;    }    public Sentinel getSentinel() {        return this.sentinel;    }    public void setSentinel(Sentinel sentinel) {        this.sentinel = sentinel;    }    public Pool getPool() {        return this.pool;    }    public void setPool(Pool pool) {        this.pool = pool;    }    /**     * Pool properties.     */    public static class Pool {        /**         * Max number of "idle" connections in the pool. Use a negative value to indicate         * an unlimited number of idle connections.         */        private int maxIdle = 8;        /**         * Target for the minimum number of idle connections to maintain in the pool.

Use a negative value         * to block indefinitely.         */        private int maxWait = -1;        public int getMaxIdle() {            return this.maxIdle;        }        public void setMaxIdle(int maxIdle) {            this.maxIdle = maxIdle;        }        public int getMinIdle() {            return this.minIdle;        }        public void setMinIdle(int minIdle) {            this.minIdle = minIdle;        }        public int getMaxActive() {            return this.maxActive;        }        public void setMaxActive(int maxActive) {            this.maxActive = maxActive;        }        public int getMaxWait() {            return this.maxWait;        }        public void setMaxWait(int maxWait) {            this.maxWait = maxWait;        }    }    /**     * Redis sentinel properties.     */    public static class Sentinel {        /**         * Name of Redis server.         */        private String master;        /**         * Comma-separated list of host:port pairs.         */        private String nodes;        public String getMaster() {            return this.master;        }        public void setMaster(String master) {            this.master = master;        }        public String getNodes() {            return this.nodes;        }        public void setNodes(String nodes) {            this.nodes = nodes;        }    }}
