ssm框架整合步骤 2017-09-23 22:24:13
一、导包（大概30个左右）
二、创建po类
三、创建mapper接口 和映射文件（可用逆向工程生成）
四、创建SqlMapperContext.xml全局配置文件
<?xml version="1.0" encoding="UTF-8" ?> <!DOCTYPE configuration PUBLIC "-//mybatis.org//DTD Config 3.0//EN" "http://www.mybatis.org/dtd/mybatis-3-config.dtd"> <configuration> <typeAliases> <package name="com.fjm.ssm.po"/> </typeAliases> </configuration>
五、配置applicationContext-dao.xml
配置内容包括数据源和sqlSessionFactory
<?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:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx" xmlns:context="http://www.springframework.org/schema/context" xsi:schemaLocation=" http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd "> <!-- <context:component-scan base-package="com.fjm.mapper"></context:component-scan> --> <!-- 配置spring的公共模块 --> <!-- 1 加载properties文件 --> <context:property-placeholder location="classpath:jdbcInfo.properties"/> <!-- 2 配置数据源 --> <bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource"> <property name="driverClass" value="${jdbc.driverClass}"></property> <property name="jdbcUrl" value="${jdbc.jdbcUrl}"></property> <property name="user" value="${jdbc.user}"></property> <property name="password" value="${jdbc.password}"></property> </bean> <!--配置SqlSessionFactory --> <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean"> <!--加载全局配置文件 --> <property name="configLocation" value="classpath:mybatis/SqlMapConfig.xml"></property> <!--引入数据源 --> <property name="dataSource" ref="dataSource"></property> </bean> <!--批量 代理mapper 会加载mapper目录下的映射文件和接口--> <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer"> <property name="basePackage" value="com.fjm.ssm.mapper"></property> </bean> </beans>
六、创建service接口和实现类，调用mapper接口实现数据调用
package com.fjm.ssm.service; import java.util.List; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.stereotype.Service; import com.fjm.ssm.mapper.ItemsExtMapper; import com.fjm.ssm.po.Items; import com.fjm.ssm.po.ItemsQuery; @Service public class ItemsServiceImpl implements ItemsService { @Autowired private ItemsExtMapper mapper; @Override public List<Items> queryItemsByItemsQuery(ItemsQuery vo) { return mapper.ItemsQuery(vo); } }
七、配置applicationContext-service.xml,实现service层的事务管理
<?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:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx" xmlns:context="http://www.springframework.org/schema/context" xsi:schemaLocation=" http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd "> <!--扫描service里的方法进行事件控制 --> <context:component-scan base-package="com.fjm.ssm.service"></context:component-scan> <!--配置事务管理器 --> <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager"> <property name="dataSource" ref="dataSource"></property> </bean> <!--配置通知 --> <tx:advice id="txAdvice" transaction-manager="transactionManager"> <tx:attributes> <!-- 传播特性 --> <tx:method name="save*" propagation="REQUIRED" /> <tx:method name="add*" propagation="REQUIRED" /> <tx:method name="insert*" propagation="REQUIRED" /> <tx:method name="delete*" propagation="REQUIRED" /> <tx:method name="del*" propagation="REQUIRED" /> <tx:method name="remove*" propagation="REQUIRED" /> <tx:method name="update*" propagation="REQUIRED" /> <tx:method name="modify*" propagation="REQUIRED" /> <tx:method name="find*" read-only="true" /> <tx:method name="query*" read-only="true" /> <tx:method name="select*" read-only="true" /> <tx:method name="get*" read-only="true" /> </tx:attributes> </tx:advice> <!--配置切面 --> <aop:config> <aop:advisor advice-ref="txAdvice" pointcut="execution(* com.fjm.ssm.service.*.*(..))"/> </aop:config> </beans>
八、配置springmvc.xml配置文件来配置controller的 业务访问处理
<beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:mvc="http://www.springframework.org/schema/mvc" xmlns:context="http://www.springframework.org/schema/context" xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.2.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.2.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.2.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.2.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.2.xsd "> <!--扫描，使该包下的注解生效 --> <context:component-scan base-package="com.fjm.ssm.controller"></context:component-scan> <!--处理器映射器和适配器 --> <mvc:annotation-driven/> <!-- 配置视图解析器 --> <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"> <property name="prefix" value="/WEB-INF/"></property> <property name="suffix" value=".jsp"></property> </bean> </beans>
九、配置web.xml
<?xml version="1.0" encoding="UTF-8"?> <web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"> <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/springmvc.xml</param-value> </init-param> </servlet> <servlet-mapping> <servlet-name>springmvc</servlet-name> <url-pattern>*.do</url-pattern> </servlet-mapping> <!-- 加载spring容器--> <context-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:spring/applicationContext-*.xml</param-value> </context-param> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> <welcome-file-list> <welcome-file>index.jsp</welcome-file> </welcome-file-list> </web-app>
十、创建controller 类处理业务访问操作
@Controller
public class QueryController {
@Autowired
private ItemsService service;
@RequestMapping("/generatorMethod")
public ModelAndView generatorMethod() {
。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。
}
十一、分析流程
①tomcat启动时，加载spring容器，contorller、service、mapper下的文件被加载
②调用过程 ： jsp页面 调用controller --> 被处理器拦截 --> 进入springmvc.xml --> 进入controller --> 调用 service层 --> 调用mapper接口 -->
自动生成实现类,调用映射文件,进行sql语句发送 --> 进入applicationContext-dao.xml 与数据库进行数据访问
