SSM整合--增删改查

5.1过去了，经过几天的尝试终于把SSM整合起来了。下面吧主要的配置说下，然后把源码上传上来。

 项目包结构：

配置文件我分成了spring-mvc.xml和spring-mybatis.xml；

spring-mvc.xml是spring mvc的配置

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
  xmlns:p="http://www.springframework.org/schema/p"
  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  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-3.2.xsd
    http://www.springframework.org/schema/context
    http://www.springframework.org/schema/context/spring-context-3.2.xsd
    http://www.springframework.org/schema/mvc
    http://www.springframework.org/schema/mvc/spring-mvc-3.2.xsd">
    
    <!-- 扫描文件（自动注入）,包括DAO层注入Service层，Service层注入Controller层 -->
    <context:component-scan base-package="com.demo"/>
    <!-- 默认的注解映射的支持 -->  
    <mvc:annotation-driven />
   <!-- 避免IE在ajax请求时，返回json出现下载 -->
   <bean id="jacksonMessageConverter" class="org.springframework.http.converter.json.MappingJacksonHttpMessageConverter">     
        <property name="supportedMediaTypes">
            <list>
                <value>text/html;charset=UTF-8</value>
            </list>
        </property>
    </bean>
    <!-- 静态资源(js/image)的访问 -->
<mvc:resources mapping="/css/**" location="/css/" />
<mvc:resources mapping="/images/**" location="/images/" />
<mvc:resources mapping="/js/**" location="/js/" />
<mvc:resources mapping="/Ext/**" location="/Ext/" />
     
   <!-- 对模型视图添加前后缀 -->
     <bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver"
      p:prefix="/WEB-INF/jsp/" p:suffix=".jsp"/>
</beans>

spring-mybatis.xml是spring和mybatis整合的配置和事务管理的配置;数据源的配置我放在了tomcat中

<?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:util="http://www.springframework.org/schema/util"
xsi:schemaLocation="http://www.springframework.org/schema/beans
    http://www.springframework.org/schema/beans/spring-beans-3.2.xsd
    http://www.springframework.org/schema/context

    http://www.springframework.org/schema/util 
    http://www.springframework.org/schema/util/spring-util-3.2.xsd">
    
<!--本示例采用DBCP连接池。 连接池配置如下 -->
<bean id="dataSource" class="org.springframework.jndi.JndiObjectFactoryBean">
<property name="jndiName" value="java:comp/env/jdbc/user" />
</bean>


<!-- mybatis文件配置，扫描所有mapper文件 -->
<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean"
p:dataSource-ref="dataSource" p:configLocation="classpath:conf/mybatis-config.xml"
p:mapperLocations="classpath:mapper/*.xml" /><!-- configLocation为mybatis属性 
mapperLocations为所有mapper -->


<!-- spring与mybatis整合配置，扫描所有dao ,生成与DAO类相同名字的bean（除了首字母小写）-->
<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer"
p:basePackage="com.demo.dao" p:sqlSessionFactoryBeanName="sqlSessionFactory" />


<bean id="userService" 
class="com.demo.service.impl.UserServiceImpl">
</bean>


<!-- 对数据源进行事务管理 -->
<bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager"
p:dataSource-ref="dataSource" />
<tx:annotation-driven mode="proxy" transaction-manager="transactionManager" />
</beans>

在controller中有登录、增、删、改、查主要的方法就不一一介绍了下面会把源码上传的，有兴趣的可以看看。

}

tomcat数据源配置

conf中的context.xml中增加

<Resource
   name="jdbc/user"
   auth="Container"
   type="javax.sql.DataSource"
   maxActive="100"
   maxIdle="30"
   maxWait="10000"
   driverClassName="com.mysql.jdbc.Driver"
   username="root"
   password=""
   url="jdbc:mysql://127.0.0.1:3306/mysql"/>

项目中的web增加

<resource-ref>
     <description>jdbc_user</description>
      <res-ref-name>jdbc/user</res-ref-name>
      <res-type>javax.sql.DataSource</res-type>
      <res-auth>Container</res-auth>
  </resource-ref>

datasoure配置

<bean id="dataSource" class="org.springframework.jndi.JndiObjectFactoryBean">
<property name="jndiName" value="java:comp/env/jdbc/user" />
</bean>
