框架集合之Spring、Ibatis和Struts2

第一步：導入相關Jar包：

第二步：配置相關配置文件
jdbc.properties

driverName=com.mysql.jdbc.Driver
url=jdbc\:mysql\://localhost\:3306/test
username=root
password=123456

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"

    xsi:schemaLocation="http://www.springframework.org/schema/beans

        http://www.springframework.org/schema/context 
        http://www.springframework.org/schema/context/spring-context-2.5.xsd
        http://www.springframework.org/schema/tx

    <!-- 讀取配置文件(必須添加相應的名字空間（context）) -->
    <context:property-placeholder
        location="WEB-INF/classes/jdbc.properties" />

    <!-- 註冊action -->
    <bean id="testAction" class="com.dx.mobile_scm.test.TestAction">
        <property name="testService" ref="testService" />
    </bean>

    <!-- 註冊service服務 -->
    <bean id="testService" class="com.dx.mobile_scm.service.TestServiceImpl">
        <property name="dao" ref="dao"></property>
    </bean>

    <!-- 配置數據源 -->
    <bean id="dataSource"
        class="org.apache.commons.dbcp.BasicDataSource">
        <property name="driverClassName" value="${driverName}"></property>
        <property name="url" value="${url}"></property>
        <property name="username" value="${username}"></property>
        <property name="password" value="${password}"></property>
        <property name="maxActive" value="30"></property>
        <property name="maxIdle" value="10"></property>
        <property name="minIdle" value="5"></property>
        <property name="maxWait" value="5000"></property>
    </bean>

    <!-- 配置ibatis工廠 -->
    <bean id="sqlMapClient"
        class="org.springframework.orm.ibatis.SqlMapClientFactoryBean">
        <property name="configLocation"
            value="/WEB-INF/classes/SqlMapConfig.xml">
        </property>
        <property name="dataSource" ref="dataSource"></property>
    </bean>

    <!-- 註冊Dao -->
    <bean id="dao" class="com.dx.mobile_scm.dao.CommonDaoImpl">
        <property name="sqlMapClient" ref="sqlMapClient"></property>
    </bean>
</beans>

第三步：測試
CommonDao.java

package com.dx.mobile_scm.dao;
public interface CommonDao {
    public Object queryForObject(String sqlId, Object parameter);
}

CommonDaoImpl.java

package com.dx.mobile_scm.dao;
import java.sql.SQLException;
import org.springframework.orm.ibatis.SqlMapClientTemplate;
public class CommonDaoImpl extends SqlMapClientTemplate implements CommonDao {
    @Override
    public Object queryForObject(String sqlId, Object parameter) {
        Object o = null;
        try {
            o =  getSqlMapClient().queryForObject(sqlId, parameter);
        } catch (SQLException e) {
            e.printStackTrace();
        }
        return o;
    }
}

在Service層調用dao

package com.dx.mobile_scm.service;
import com.dx.mobile_scm.dao.CommonDao;
import com.dx.mobile_scm.test.User;
public class TestServiceImpl implements TestService {
    private CommonDao dao;
    public void setDao(CommonDao dao) {
        this.dao = dao;
    }
    public String validate(){
        System.out.println(dao);
        User u = (User) dao.queryForObject("findUser", 3);
        System.out.println(u.getName());
        return "hello world";
    }
}
