SSM整合
SSM整合
工程结构！
- 配置Spring
- 表头

http://www.springframework.org/schema/context/spring-context.xsd">
</beans>
- 配置注解扫描（无需扫描controller层）
<context:component-scan base-package="com.boerk">
<context:exclude-filter type="annotation" expression="org.springframework.stereotype.Controller"/>
</context:component-scan>
- 配置数据源信息（整合mybatis）
<!--引入外部文件-->
<context:property-placeholder location="classpath:jdbc.properties"/>
<!--配置数据源信息-->
<bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">
<property name="driverClass" value="${jdbc.driver}"></property>
<property name="jdbcUrl" value="${jdbc.url}"></property>
<property name="user" value="${jdbc.username}"></property>
<property name="password" value="${jdbc.password}"></property>
</bean>
- 配置sqlSessionFactory（需要spring整合mybatis的依赖）
<!--配置sqlSessionFactory信息-->
<bean id="sessionFactoryBean" class="org.mybatis.spring.SqlSessionFactoryBean">
<property name="dataSource" ref="dataSource"></property>
<property name="configLocation" value="classpath:sqlMapConfig.xml"></property>
</bean>
<!--配置扫描mapper接口-->
<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
<property name="basePackage" value="com.boerk.mapper"></property>
</bean>
- 配置spring事务管理
<!-- 声明式事务管理器-->
<bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
<property name="dataSource" ref="dataSource"></property>
</bean>
- 配置事务增强
<!--事务增强-->
<tx:advice id="txAdvice">
<tx:attributes>
<tx:method name="*"/>
</tx:attributes>
</tx:advice>
<!--事务的aop,可以使用注解方式。-->
<aop:config>
<aop:advisor advice-ref="txAdvice" pointcut="execution(* com.boerk.service.*.*(..))"></aop:advisor>
</aop:config>
- 配置SpringMVC
- 表头
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:mvc="http://www.springframework.org/schema/mvc"
xmlns:context="http://www.springframework.org/schema/context"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans.xsd
http://www.springframework.org/schema/mvc
http://www.springframework.org/schema/mvc/spring-mvc.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context.xsd">
</beans>
- 配置注解扫描（只扫描Controller层）
<context:component-scan base-package="com.boerk.controller"/>
- 配置注解驱动
<mvc:annotation-driven/>
- 配置视图解析器（以jsp举例）
<bean id="resourceViewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix" value="/WEB-INF/pages/"/>
<property name="suffix" value=".jsp"/>
</bean>
thymeleaf
<!-- 配置Thymeleaf视图解析器 -->
<bean id="viewResolver" class="org.thymeleaf.spring5.view.ThymeleafViewResolver">
<property name="order" value="1"/>
<property name="characterEncoding" value="UTF-8"/>
<property name="templateEngine">
<bean class="org.thymeleaf.spring5.SpringTemplateEngine">
<property name="templateResolver">
<bean class="org.thymeleaf.spring5.templateresolver.SpringResourceTemplateResolver">
<!-- 视图前缀 -->
<property name="prefix" value="/WEB-INF/templates/"/>
<!-- 视图后缀 -->
<property name="suffix" value=".html"/>
<property name="templateMode" value="HTML5"/>
<property name="characterEncoding" value="UTF-8" />
</bean>
</property>
</bean>
</property>
</bean>
- 配置开放对静态资源的访问
<mvc:default-servlet-handler/>
- mybatis配置
<!DOCTYPE configuration
PUBLIC "-//mybatis.org//DTD Config 3.0//EN"
"http://mybatis.org/dtd/mybatis-3-config.dtd">
<configuration>
<!--定义别名-->
<typeAliases>
<package name="com.boerk.pojo"></package>
</typeAliases>
</configuration>
- web.xml配置
- 表头
<web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_4_0.xsd"
version="4.0">
</web-app>
- 配置contextConfigLocation
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:applicationContext.xml</param-value>
</context-param>
- 配置监听器
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
- 配置前端控制器
<servlet>
<servlet-name>DispatcherServlet</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>
</servlet>
<servlet-mapping>
<servlet-name>DispatcherServlet</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>
- 配置过滤器，来处理乱码问题（需配置encoding和forceResponseEncoding）
如果是jsp页面则需要设置@RequestMapping(value = "/save",produces = "text/html;charset=UTF-8")
<filter>
<filter-name>CharacterEncodingFilter</filter-name>
<filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
<init-param>
<param-name>encoding</param-name>
<param-value>UTF-8</param-value>
</init-param>
</filter>
<filter-mapping>
<filter-name>CharacterEncodingFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
