ssm框架整合筆記-1-基礎框架搭建，ssm-1-

准備工作

新建項目，規劃好各層的包，並導入所需jar包

開始整合

1.整合spring和mybatis

創建編寫配置文件

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>
    <!-- 通過別名簡化對類的使用 
    <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"

    http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.2.xsd">

    
    <!-- 配置數據源，記得去掉myBatis-config.xml的數據源相關配置 -->
    <bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">            
        <property name="driverClass" value="com.mysql.jdbc.Driver" />

    </bean>
    
    <!-- 配置事務管理器,管理數據源事務處理-->
    <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
        <property name="dataSource" ref="dataSource" />

    <!-- 配置事務通知 -->
    <tx:advice id="advice" transaction-manager="transactionManager">

        </tx:attributes>
    </tx:advice>
    <!-- 配置切面織入的范圍,後邊要把事務邊界定在service層 -->
    <aop:config>
        <aop:advisor advice-ref="advice" pointcut="execution(* cn.itcast.scm.dao.impl.*.*(..))"/>
    </aop:config>
    <!-- 配置SessionTemplate，已封裝了繁瑣的數據操作-->
    <bean id="sqlSessionTemplate" class="org.mybatis.spring.SqlSessionTemplate">
        <constructor-arg name="sqlSessionFactory" ref="sqlSessionFactory"/>        
    </bean>
    
    <context:component-scan base-package="*"/>
        
</beans>

1.3 編寫實體及sql映射文件

1.3.1 sql 腳本，插入測試數據

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('研發部一部','廣州');
insert into dept(dept_name,dept_address) values('研發部二部','廣州');
insert into dept(dept_name,dept_address) values('研發部三部','深圳');

select * from dept;

1.3.2 編寫實體類

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和命名空間用來定位SQL語句，parameterType表示參數的類型，resultMap返回類型 -->
    <select id="selectDept" parameterType="Integer" resultMap="deptResultMap">
        <!--參數的寫法#{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文件修改後為如下內容

<?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>
    <!-- 通過別名簡化對類的使用 -->
    <typeAliases>
        <typeAlias type="cn.itcast.scm.entity.Dept" alias="Dept" />
    </typeAliases>
    <mappers>
        <mapper resource="cn/itcast/scm/entity/DeptMapper.xml" />
    </mappers>

</configuration>

2.編寫Dao接口及實現

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;

    /**
     * 根據部門編號查詢部門信息
     * 
     * @param deptId
     *            部門編號
     * @return 部門信息
     */
    public Dept selectDept(Integer deptId) {
        Dept dept = sqlSessionTemplate.selectOne(
                "cn.itcast.scm.entity.DeptMapper.selectDept", deptId);
        return dept;
    }

    /**
     * 添加部門信息
     * 
     * @param dept
     *            部門信息
     * @return 添加成功的記錄數
     */
    public int insertDept(Dept dept) {
        System.out.println("------dao.dept:" + dept);
        return sqlSessionTemplate.insert(
                "cn.itcast.scm.entity.DeptMapper.insertDept", dept);
    }

}

3.測試spring與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 //這裡沒法使用，後繼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("受影響行數："+deptDao.insertDept(dept));
        }


}

4. 整合springmvc

修改web.xml文件，加入springmvc相關信息，編寫控制器類及相關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. 編寫控制器類

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 //這裡沒法使用，後繼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("受影響行數："+deptDao.insertDept(dept));
        }


}

6. 編寫跳轉頁面

/jsp/main.jsp

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

7. 測試ssi整合

編寫測試頁面index.jsp

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