Spring Boot 1.4.3搭建

做项目时候，为了分出一个获取统一token的模块，采用spring boot进行项目构建。

pom.xml文件内容如下：

<?xml version="1.0" encoding="UTF-8"?><project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">    <modelVersion>4.0.0</modelVersion>    <groupId>com.vi</groupId>    <artifactId>personal</artifactId>    <version>1.0-SNAPSHOT</version>    <packaging>war</packaging>    <!-- 继承父包 -->    <parent>        <groupId>org.springframework.boot</groupId>        <artifactId>spring-boot-starter-parent</artifactId>        <version>1.4.3.RELEASE</version>    </parent>    <!-- spring-boot的web启动的jar包 -->    <dependencies>        <dependency>            <groupId>org.springframework.boot</groupId>            <artifactId>spring-boot-starter-web</artifactId>        </dependency>        <!--jpa的jar包 ，操作数据库的，类似hibernate-->        <dependency>            <groupId>org.springframework.boot</groupId>            <artifactId>spring-boot-starter-data-jpa</artifactId>        </dependency>        <!--mysql驱动-->        <dependency>            <groupId>mysql</groupId>            <artifactId>mysql-connector-java</artifactId>        </dependency>        <!--thymeleaf模板jar，是很不错的html数据传递取值，类似jsp的jstl-->        <dependency>            <groupId>org.springframework.boot</groupId>            <artifactId>spring-boot-starter-thymeleaf</artifactId>        </dependency>        <dependency>            <groupId>com.microsoft.sqlserver</groupId>            <artifactId>sqljdbc4</artifactId>            <version>4.0</version>            <scope>system</scope>            <systemPath>${project.basedir}/src/main/lib/sqljdbc4.jar</systemPath>        </dependency>    </dependencies>    <!--maven的插件-->    <build>        <plugins>            <plugin>                <groupId>org.springframework.boot</groupId>                <artifactId>spring-boot-maven-plugin</artifactId>            </plugin>        </plugins>        <!-- 配置java版本 不配置的话默认父类配置的是1.6-->        <pluginManagement>            <plugins>                <plugin>                    <artifactId>maven-compiler-plugin</artifactId>                    <configuration>                        <source>1.7</source>                        <target>1.7</target>                    </configuration>                </plugin>            </plugins>        </pluginManagement>    </build></project>

因为使用了sqlserver数据库，所以添加了sqlserver驱动部分内容。

在resources文件夹下防止配置文件，application.properties:

spring.datasource.platform=mysqlspring.datasource.url=spring.datasource.username=spring.datasource.password=spring.datasource.driverClassName=com.microsoft.sqlserver.jdbc.SQLServerDriver# Advanced configuration...spring.datasource.max-active=50spring.datasource.max-idle=6spring.datasource.min-idle=2spring.datasource.initial-size=6#create tablespring.jpa.hibernate.ddl-auto= validateserver.port=8888server.session-timeout=30server.tomcat.uri-encoding=UTF-8spring.thymeleaf.prefix=classpath:templates/spring.thymeleaf.suffix=.htmlspring.thymeleaf.mode=HTML5spring.thymeleaf.encoding=UTF-8spring.thymeleaf.content-type=text/htmlspring.thymeleaf.cache=false

---

定义的controller内容：

package mk.controller;import org.springframework.boot.SpringApplication;import org.springframework.boot.autoconfigure.EnableAutoConfiguration;import org.springframework.context.annotation.ComponentScan;import org.springframework.stereotype.Controller;import org.springframework.web.bind.annotation.RequestMapping;import org.springframework.web.bind.annotation.ResponseBody;import org.springframework.web.bind.annotation.RestController;/** * Created by yangyang on 17/1/26. */@RestControllerpublic class WeController {    @RequestMapping(value = "/")    public String index() {        return "welcome";    }}

---

定义application，作为spring boot入口。springboot同样要去指定的目录下扫描controller，service等各种组建来进行依赖注入，这部分的配置可以在入口通过componetScan指定扫描包名，不然无法找到相应的bean。运行Application的main方法，注意看到我们的 weController 是否成功启动。

package mk.boot;import org.springframework.boot.CommandLineRunner;import org.springframework.boot.SpringApplication;import org.springframework.boot.autoconfigure.EnableAutoConfiguration;import org.springframework.boot.autoconfigure.SpringBootApplication;import org.springframework.context.ApplicationContext;import org.springframework.context.annotation.Bean;import org.springframework.context.annotation.ComponentScan;import org.springframework.context.annotation.Configuration;import java.util.Arrays;/** * Created by yangyang on 17/1/26. */@SpringBootApplication@ComponentScan(value = {"mk.controller"})public class Application {    public static void main(String[] args) {        SpringApplication.run(Application.class, args);    }    @Bean    public CommandLineRunner commandLineRunner(final ApplicationContext ctx) {        return new CommandLineRunner() {            @Override            public void run(String... strings) throws Exception {                System.out.println("Let's inspect the beans provided by Spring Boot:");                String[] beanNames = ctx.getBeanDefinitionNames();                Arrays.sort(beanNames);                for (String beanName : beanNames) {                    System.out.println(beanName);                }            }        };    }}

直接访问localhost:8888 即可看到我们的welcome页面。

以上通过spring boot，相当于整合了spring和spring mvc构建了一个基本的框架，但是数据访问层还没有进行整合，可以采用mybatis等。
