ssm框架整合笔记-1-基础框架搭建

准备工作

新建项目，规划好各层的包，并导入所需jar包

开始整合

1.整合spring和mybatis

创建编写配置文件

applicationContext.xml
myBatis-config.xml
spring-mvc.xml
log4j.properties

1.1 myBatis-config.xml文件

<?xml version="1.0" encoding="UTF-8" ?> 
<!DOCTYPE configuration PUBLIC "-//mybatis.org//DTD Config 3.0//EN" 
"http://mybatis.org/dtd/mybatis-3-config.dtd">
<configuration>
    <!-- 通过别名简化对类的使用 
    <typeAliases>
        <typeAlias type="cn.itcast.scm.entity.Dept" alias="Dept" />
    </typeAliases>
    <mappers>
        <mapper resource="cn/itcast/scm/entity/DeptMapper.xml" />
    </mappers>
    -->
</configuration>

1.2 applicationContext.xml

<?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:tx="http://www.springframework.org/schema/tx"
    xmlns:aop="http://www.springframework.org/schema/aop"
    xmlns:context="http://www.springframework.org/schema/context"
    xmlns:p="http://www.springframework.org/schema/p"
    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/tx 
    http://www.springframework.org/schema/tx/spring-tx-3.2.xsd
    http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.2.xsd">

    
    <!-- 配置数据源，记得去掉myBatis-config.xml的数据源相关配置 -->
    <bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">            
        <property name="driverClass" value="com.mysql.jdbc.Driver" />
        <property name="jdbcUrl" value="jdbc:mysql://localhost:3306/test?useUnicode=true&amp;characterEncoding=UTF-8" />
        <property name="user" value="root" />
        <property name="password" value="root" />        
    </bean>
    <!-- 配置session工厂 -->
    <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
        <property name="dataSource" ref="dataSource" />
        <property name="configLocation" value="classpath:myBatis-config.xml" />
    </bean>
    
    <!-- 配置事务管理器,管理数据源事务处理-->
    <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
        <property name="dataSource" ref="dataSource" />
    </bean>
    <!-- 配置事务通知 -->
    <tx:advice id="advice" transaction-manager="transactionManager">
        <tx:attributes>
<!-- 默认只处理运行时异常，可加rollback-for="Exception/Throwable"等处理所有异常或包括错误 -->
            <tx:method name="insert*" propagation="REQUIRED" rollback-for="Exception"/>
            <tx:method name="update*" propagation="REQUIRED" rollback-for="Exception"/>
            <tx:method name="delete*" propagation="REQUIRED" rollback-for="Exception"/>
            <tx:method name="*" propagation="SUPPORTS"/>
        </tx:attributes>
    </tx:advice>
    <!-- 配置切面织入的范围,后边要把事务边界定在service层 -->
    <aop:config>
        <aop:advisor advice-ref="advice" pointcut="execution(* cn.itcast.scm.dao.impl.*.*(..))"/>
    </aop:config>
    <!-- 配置SessionTemplate，已封装了繁琐的数据操作-->
    <bean id="sqlSessionTemplate" class="org.mybatis.spring.SqlSessionTemplate">
        <constructor-arg name="sqlSessionFactory" ref="sqlSessionFactory"/>        
    </bean>
    
    <context:component-scan base-package="*"/>
        
</beans>

1.3 编写实体及sql映射文件

1.3.1 sql 脚本，插入测试数据

drop database if exists test;
create database test CHARACTER SET UTF8;
use mybatis;

create table dept(
    dept_id int primary key auto_increment,
    dept_name varchar(50),
    dept_address varchar(50)
);


insert into dept(dept_name,dept_address) values('研发部一部','广州');
insert into dept(dept_name,dept_address) values('研发部二部','广州');
insert into dept(dept_name,dept_address) values('研发部三部','深圳');

select * from dept;

1.3.2 编写实体类

package cn.itcast.scm.entity;

import java.io.Serializable;

public class Dept implements Serializable {

    /**
     * 
     */
    private static final long serialVersionUID = 807184188547688524L;
    private Integer deptId;
    private String deptName;
    private String deptAddress;

    public Integer getDeptId() {
        return deptId;
    }

    public void setDeptId(Integer deptId) {
        this.deptId = deptId;
    }

    public String getDeptName() {
        return deptName;
    }

    public void setDeptName(String deptName) {
        this.deptName = deptName;
    }

    public String getDeptAddress() {
        return deptAddress;
    }

    public void setDeptAddress(String deptAddress) {
        this.deptAddress = deptAddress;
    }

    @Override
    public String toString() {
        return "Dept [deptId=" + deptId + ", deptName=" + deptName
                + ", deptAddress=" + deptAddress + "]";
    }

}

1.3.3 SQL映射文件

<?xml version="1.0" encoding="UTF-8" ?> 
<!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd">

<mapper namespace="cn.itcast.scm.entity.DeptMapper">
    <resultMap type="Dept" id="deptResultMap">
        <id property="deptId" column="dept_id" />
        <result property="deptName" column="dept_name" />
        <result property="deptAddress" column="dept_address" />
    </resultMap>
    <!-- id和命名空间用来定位SQL语句，parameterType表示参数的类型，resultMap返回类型 -->
    <select id="selectDept" parameterType="Integer" resultMap="deptResultMap">
        <!--参数的写法#{deptID} -->
        select dept_id,dept_name,dept_address from dept where dept_id=#{deptID}
    </select>

    <insert id="insertDept" parameterType="Dept">
        insert into dept(dept_name,dept_address) values(#{deptName},#{deptAddress});
    </insert>

</mapper>

1.3.4 myBatis-config.xml文件修改后为如下内容

<?xml version="1.0" encoding="UTF-8" ?> 
<!DOCTYPE configuration PUBLIC "-//mybatis.org//DTD Config 3.0//EN" 
"http://mybatis.org/dtd/mybatis-3-config.dtd">
<configuration>
    <!-- 通过别名简化对类的使用 -->
    <typeAliases>
        <typeAlias type="cn.itcast.scm.entity.Dept" alias="Dept" />
    </typeAliases>
    <mappers>
        <mapper resource="cn/itcast/scm/entity/DeptMapper.xml" />
    </mappers>

</configuration>

2.编写Dao接口及实现

DeptDaoImpl.java

package cn.itcast.scm.dao.impl;

import javax.annotation.Resource;

import org.mybatis.spring.SqlSessionTemplate;
import org.springframework.stereotype.Repository;

import cn.itcast.scm.entity.Dept;

@Repository("deptDao")
public class DeptDaoImpl {
    @Resource
    private SqlSessionTemplate sqlSessionTemplate;

    /**
     * 根据部门编号查询部门信息
     * 
     * @param deptId
     *            部门编号
     * @return 部门信息
     */
    public Dept selectDept(Integer deptId) {
        Dept dept = sqlSessionTemplate.selectOne(
                "cn.itcast.scm.entity.DeptMapper.selectDept", deptId);
        return dept;
    }

    /**
     * 添加部门信息
     * 
     * @param dept
     *            部门信息
     * @return 添加成功的记录数
     */
    public int insertDept(Dept dept) {
        System.out.println("------dao.dept:" + dept);
        return sqlSessionTemplate.insert(
                "cn.itcast.scm.entity.DeptMapper.insertDept", dept);
    }

}

3.测试spring与mybatis整合

package cn.itcast.scm.test;

import org.junit.AfterClass;
import org.junit.BeforeClass;
import org.junit.Test;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;

import cn.itcast.scm.dao.impl.DeptDaoImpl;
import cn.itcast.scm.entity.Dept;

public class TestDeptDao {

    //@Resource //这里没法使用，后继版本有其它方式可以注入
        static private DeptDaoImpl deptDao;
        @BeforeClass
        public static void setUpBeforeClass() throws Exception {
            ApplicationContext context =new ClassPathXmlApplicationContext("applicationContext.xml");
            deptDao=(DeptDaoImpl) context.getBean("deptDao");
        }

        @AfterClass
        public static void tearDownAfterClass() throws Exception {
        }

        @Test
        public void testSelectDept() {
            System.out.println(deptDao.selectDept(1));
        }

        @Test
        public void testInsertDept() {
            Dept dept=new Dept();
            //dept.setDeptId(117);
            dept.setDeptName("name118");
            dept.setDeptAddress("address118");
            System.out.println("受影响行数："+deptDao.insertDept(dept));
        }


}

4. 整合springmvc

修改web.xml文件，加入springmvc相关信息，编写控制器类及相关jsp 文件

4.1 spring-mvc.xml

<?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:mvc="http://www.springframework.org/schema/mvc"
    xmlns:context="http://www.springframework.org/schema/context"
    xmlns:p="http://www.springframework.org/schema/p"
    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
    ">
            
    <mvc:annotation-driven></mvc:annotation-driven>
    <context:component-scan base-package="*"/>
</beans>

4.2 web.xml文件配置

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="3.0" 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_3_0.xsd">
    <display-name></display-name>
    <welcome-file-list>
        <welcome-file>index.jsp</welcome-file>
    </welcome-file-list>

    <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener>
    <context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>classpath:applicationContext.xml</param-value>
    </context-param>
    <servlet>
        <servlet-name>mvc</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>mvc</servlet-name>
        <url-pattern>*.action</url-pattern>
    </servlet-mapping>
    <filter>
        <filter-name>encodingFilter</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>encodingFilter</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>

</web-app>

5. 编写控制器类

DeptAction.java

package cn.itcast.scm.test;

import org.junit.AfterClass;
import org.junit.BeforeClass;
import org.junit.Test;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;

import cn.itcast.scm.dao.impl.DeptDaoImpl;
import cn.itcast.scm.entity.Dept;

public class TestDeptDao {

    //@Resource //这里没法使用，后继版本有其它方式可以注入
        static private DeptDaoImpl deptDao;
        @BeforeClass
        public static void setUpBeforeClass() throws Exception {
            ApplicationContext context =new ClassPathXmlApplicationContext("applicationContext.xml");
            deptDao=(DeptDaoImpl) context.getBean("deptDao");
        }

        @AfterClass
        public static void tearDownAfterClass() throws Exception {
        }

        @Test
        public void testSelectDept() {
            System.out.println(deptDao.selectDept(1));
        }

        @Test
        public void testInsertDept() {
            Dept dept=new Dept();
            //dept.setDeptId(117);
            dept.setDeptName("name118");
            dept.setDeptAddress("address118");
            System.out.println("受影响行数："+deptDao.insertDept(dept));
        }


}

6. 编写跳转页面

/jsp/main.jsp

<%@ page language="java" import="java.util.*" pageEncoding="utf-8"%>
<html>
<head>
</head>
<body>this is main jsp
</body>
</html>

7. 测试ssi整合

编写测试页面index.jsp

<%@ page language="java" import="java.util.*" pageEncoding="utf-8"%>
<html>
<head>
</head>
<body>
    <form action="dept/insert.action" method="post">
        名称：<input type="text" name="deptName"><br> 
        地址：<input     type="text" name="deptAddress"><br> 
        <input type="submit" value="ok">
    </form>
</body>
</html>
