搭建环境
1.配置pom依赖jar
<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/maven-v4_0_0.xsd"> <modelVersion>4.0.0</modelVersion> <groupId>com.lzj.test</groupId> <artifactId>springMvc</artifactId> <packaging>war</packaging> <version>0.0.1-SNAPSHOT</version> <name>springMvc Maven Webapp</name> <url>http://maven.apache.org</url> <properties> <!-- spring版本号 --> <spring.version>4.0.2.RELEASE</spring.version> <!-- mybatis版本号 --> <mybatis.version>3.2.6</mybatis.version> <!-- log4j日志文件管理包版本 --> <slf4j.version>1.7.7</slf4j.version> <log4j.version>1.2.17</log4j.version> </properties> <dependencies> <dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> <version>4.11</version> <!-- 表示开发的时候引入，发布的时候不会加载此包 --> <scope>test</scope> </dependency> <!-- spring核心包 --> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-core</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-web</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-oxm</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-tx</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-jdbc</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-webmvc</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-aop</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-context-support</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-test</artifactId> <version>${spring.version}</version> </dependency> <!-- mybatis核心包 --> <dependency> <groupId>org.mybatis</groupId> <artifactId>mybatis</artifactId> <version>${mybatis.version}</version> </dependency> <!-- mybatis/spring包 --> <dependency> <groupId>org.mybatis</groupId> <artifactId>mybatis-spring</artifactId> <version>1.2.2</version> </dependency> <!-- 导入java ee jar 包 --> <dependency> <groupId>javax.servlet</groupId> <artifactId>javax.servlet-api</artifactId> <version>3.1.0</version> <scope>provided</scope> </dependency> <!-- 导入Mysql数据库链接jar包 --> <dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> <version>5.1.30</version> </dependency> <!-- 导入dbcp的jar包，用来在applicationContext.xml中配置数据库 --> <dependency> <groupId>commons-dbcp</groupId> <artifactId>commons-dbcp</artifactId> <version>1.2.2</version> </dependency> <!-- JSTL标签类 --> <dependency> <groupId>jstl</groupId> <artifactId>jstl</artifactId> <version>1.2</version> </dependency> <!-- 日志文件管理包 --> <!-- log start --> <dependency> <groupId>log4j</groupId> <artifactId>log4j</artifactId> <version>${log4j.version}</version> </dependency> <dependency> <groupId>org.slf4j</groupId> <artifactId>slf4j-api</artifactId> <version>${slf4j.version}</version> </dependency> <dependency> <groupId>com.alibaba</groupId> <artifactId>fastjson</artifactId> <version>1.1.41</version> </dependency> <dependency> <groupId>org.slf4j</groupId> <artifactId>slf4j-log4j12</artifactId> <version>${slf4j.version}</version> </dependency> <!-- log end --> <!-- 映入JSON --> <dependency> <groupId>org.codehaus.jackson</groupId> <artifactId>jackson-mapper-asl</artifactId> <version>1.9.13</version> </dependency> <!-- 上传组件包 --> <dependency> <groupId>commons-fileupload</groupId> <artifactId>commons-fileupload</artifactId> <version>1.3.1</version> </dependency> <dependency> <groupId>commons-io</groupId> <artifactId>commons-io</artifactId> <version>2.4</version> </dependency> <dependency> <groupId>commons-codec</groupId> <artifactId>commons-codec</artifactId> <version>1.9</version> </dependency> </dependencies> <build> <finalName>springMvc</finalName> <resources> <resource> <directory>src/main/resources</directory> <includes> <include>**/*.*</include> </includes> </resource> </resources> </build> <repositories> <repository> <releases> <enabled>true</enabled> <updatePolicy>always</updatePolicy> <checksumPolicy>fail</checksumPolicy> </releases> <id>internal</id> <name>Tom Central Maven Repository</name> <layout>default</layout> <url>http://xxx/artifactory/repo</url> <snapshots> <updatePolicy>always</updatePolicy> <checksumPolicy>warn</checksumPolicy> </snapshots> </repository> </repositories></project>2.配置web.xml文件
<?xml version="1.0" encoding="UTF-8"?><web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xmlns="http://java.sun.com/xml/ns/javaee"xmlns:web="http://xmlns.jcp.org/xml/ns/javaee"xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"version="3.0"><display-name>Archetype Created Web Application</display-name><!-- Spring通用配置文件,包括mybatis --><context-param><param-name>contextConfigLocation</param-name><param-value>classpath:spring-mybatis.xml</param-value></context-param><!-- Spring监听器 --><listener><listener-class>org.springframework.web.context.ContextLoaderListener</listener-class></listener><!-- 编码过滤器(post请求才有效) --><filter><filter-name>encodingFilter</filter-name><filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class><async-supported>true</async-supported><init-param><param-name>encoding</param-name><param-value>UTF-8</param-value></init-param></filter><filter-mapping><filter-name>encodingFilter</filter-name><url-pattern>/*</url-pattern></filter-mapping><!-- Spring MVC servlet --><servlet><servlet-name>SpringMVC</servlet-name><servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class><init-param><param-name>contextConfigLocation</param-name><param-value>classpath:spring-mvc.xml</param-value></init-param><load-on-startup>1</load-on-startup><async-supported>true</async-supported></servlet><servlet-mapping><servlet-name>SpringMVC</servlet-name><!-- 此处可以可以配置成*.do，对应struts的后缀习惯 --><url-pattern>*.do</url-pattern></servlet-mapping><welcome-file-list><welcome-file>/index.jsp</welcome-file></welcome-file-list></web-app>
3.配置spring-mvc.xml文件
<?xml version="1.0" encoding="UTF-8"?><beans xmlns="http://www.springframework.org/schema/beans"xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:p="http://www.springframework.org/schema/p"xmlns:context="http://www.springframework.org/schema/context"xmlns:mvc="http://www.springframework.org/schema/mvc"xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.1.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.1.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd"><!-- 自动扫描该包,并且只扫描@Controller --><context:component-scan base-package="com.lzj.test" use-default-filters="false"><context:include-filter type="annotation" expression="org.springframework.stereotype.Controller"/> </context:component-scan><!-- 默认的注解映射的支持 --> <mvc:annotation-driven /> <!--避免IE执行AJAX时，返回JSON出现下载文件 --><bean id="mappingJacksonHttpMessageConverter"class="org.springframework.http.converter.json.MappingJacksonHttpMessageConverter"><property name="supportedMediaTypes"><list><value>text/html;charset=UTF-8</value></list></property></bean><!-- 启动SpringMVC的注解功能，完成请求和注解POJO的映射 --><beanclass="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter" /><!-- 定义跳转的文件的前后缀 ，视图模式配置--><bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"><!-- 这里的配置我的理解是自动给后面action的方法return的字符串加上前缀和后缀，变成一个 可用的url地址 --><property name="prefix" value="/WEB-INF/jsp/" /><property name="suffix" value=".jsp" /></bean><!-- 配置文件上传，如果没有使用文件上传可以不用配置，当然如果不配，那么配置文件中也不必引入上传组件包 --><bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver"> <!-- 默认编码 --> <property name="defaultEncoding" value="utf-8" /> <!-- 文件大小最大值 --> <property name="maxUploadSize" value="10485760000" /> <!-- 内存中的最大值 --> <property name="maxInMemorySize" value="40960" /> </bean> </beans>
4.配置spring-mybatis.xml文件
<?xml version="1.0" encoding="UTF-8"?><beans xmlns="http://www.springframework.org/schema/beans"xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:p="http://www.springframework.org/schema/p"xmlns:context="http://www.springframework.org/schema/context"xmlns:mvc="http://www.springframework.org/schema/mvc"xmlns:tx="http://www.springframework.org/schema/tx" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.1.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.1.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd"><!-- 自动扫描该包,排除@Controller --><context:component-scan base-package="com.lzj.test" ><context:exclude-filter type="annotation" expression="org.springframework.stereotype.Controller"/> </context:component-scan><!-- 引入配置文件 --><bean id="propertyConfigurer"class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer"><property name="location" value="classpath:jdbc.properties" /></bean><bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource"destroy-method="close"><property name="driverClassName" value="${driver}" /><property name="url" value="${url}" /><property name="username" value="${username}" /><property name="password" value="${password}" /><!-- 初始化连接大小 --><property name="initialSize" value="${initialSize}"></property><!-- 连接池最大数量 --><property name="maxActive" value="${maxActive}"></property><!-- 连接池最大空闲 --><property name="maxIdle" value="${maxIdle}"></property><!-- 连接池最小空闲 --><property name="minIdle" value="${minIdle}"></property><!-- 获取连接最大等待时间 --><property name="maxWait" value="${maxWait}"></property></bean><!-- spring和MyBatis完美整合，不需要mybatis的配置映射文件 --><bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean"><property name="dataSource" ref="dataSource" /><!-- 自动扫描mapping.xml文件 --><property name="mapperLocations" value="classpath:mapper/*.xml"></property></bean><!-- mybatis接口编程，Spring会自动查找其下的类 --><bean class="org.mybatis.spring.mapper.MapperScannerConfigurer"><property name="basePackage" value="com.lzj.test.mapper" /><property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"></property> </bean><!-- (事务管理)transaction manager, use JtaTransactionManager for global tx --><bean id="transactionManager"class="org.springframework.jdbc.datasource.DataSourceTransactionManager"><property name="dataSource" ref="dataSource" /></bean><!-- 注解事务 --><tx:annotation-driven transaction-manager="transactionManager" /></beans>5.配置jdbc.properties文件
driver=com.mysql.jdbc.Driverurl=jdbc:mysql://ip:port/xxx?characterEncoding=utf8username=my_userpassword=my_pwd#\u5B9A\u4E49\u521D\u59CB\u8FDE\u63A5\u6570initialSize=0#\u5B9A\u4E49\u6700\u5927\u8FDE\u63A5\u6570maxActive=20#\u5B9A\u4E49\u6700\u5927\u7A7A\u95F2maxIdle=20#\u5B9A\u4E49\u6700\u5C0F\u7A7A\u95F2minIdle=1#\u5B9A\u4E49\u6700\u957F\u7B49\u5F85\u65F6\u95F4maxWait=60000
6.最后项目结构
注:
在整合配置中，ContextLoaderListener初始化的上下文加载的Bean是对于整个应用程序共享的，不管是使用什么表现层技术，一般如DAO层、Service层Bean。对应的配置是web.xml如下部分:
<context-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:spring-mybatis.xml</param-value> </context-param> <!-- Spring监听器 --> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener>DispatcherServlet初始化的上下文加载的Bean是只对Spring Web MVC有效的Bean，如Controller、HandlerMapping、HandlerAdapter等等，该初始化上下文应该只加载Web相关组件。对应的配置是web.xml如下部分:
<servlet> <servlet-name>SpringMVC</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <init-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:spring-mvc.xml</param-value> </init-param> <load-on-startup>1</load-on-startup> <async-supported>true</async-supported> </servlet>这也是上述pring-mvc.xml配置中<context:component-scan>组件只扫描@Controller,而spring-mybatis.xml中排除扫描@Controller的一个原因,还有另一原因是事务没有配置在springmvc配置文件中，从而造成新加载的bean覆盖了老的bean，造成事务失效。
