Spring MVC + Mybatis + Spring - 整合示例1：查询所有的客户信息

2016-01-06 08:50 731 查看

1.背景

通过这么长时间的学习，终于见到了效果，确实有点乐不思蜀。虽然下面还有很多东西要学习，但是也要为自己的第一篇整合篇写下一些留念。

数据库：Oracle xe10g

表：客户信息表

场景描述：实现查询所有的客户信息；

框架：Spring　＋　Springmvc + Mybatis

Spring的作用：

表现层：springMvc

业务层：service接口

持久层：mybatis

数据库：Oracle / Mysql

Spring将各层进行整合：
1）通过Spring管理持久层的mapping（相当于dao接口）
2）通过Spring管理业务层Service,Service中可以调用Mapping接口；可以进行事务控制（AOP）
3）通过spring 管理表现层Handler，Handler中可以调用Service接口；
mapper,service，handler都是javabean ;

2.示例实现

2.1 最终效果

2.2 数据准备

（1）创建客户信息表

CREATE TABLE F_CLIENT(
ID NUMBER(12) PRIMARY KEY,--用户编号
USERNAME VARCHAR2(20) NOT NULL,--用户姓名
CLIENT_CERTIFICATE_NO VARCHAR2(20) NOT NULL UNIQUE,--证件号码
BORN_DATE DATE,--出生日期
FAMILY_REGISTER_ADDRESS VARCHAR2(200),--家庭住址
NOW_ADDRESS VARCHAR2(200) NOT NULL,--现在住址
CONTACT_MODE VARCHAR2(50) NOT NULL,--联系方式
URGENCY_CONTACT_MODE VARCHAR2(50) NOT NULL,--紧急联系方式
CREATE_DATE DATE NOT NULL--创建时间
);

（2）添加客户信息
insert into f_client(id,username,client_certificate_no,born_date,family_register_address,now_address,contact_mode,urgency_contact_mode,create_date) values (14,
'yuan','311209070127',to_date('1993-03-12','yyyy-mm-dd'),'河南省焦作市','河南省河南理工大学','150000000','110',sysdate);
insert into f_client(id,username,client_certificate_no,born_date,family_register_address,now_address,contact_mode,urgency_contact_mode,create_date) values(

sysdate)
</insert>

</mapper>

（3）sqlmapconfig.xml实现
<?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>


<typeAliases>

<typeAlias type="cn.labelnet.ssm.po.FClient" alias="fclient"/>

</typeAliases>

<mappers>




</mappers>

</configuration>

（4）Mybatis与Spring整合：实现ApplicationContext-dao.xml

<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"

<context:property-placeholder location="classpath:db.properties"/>

<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource">
<property name="driverClassName" value="${jdbc.driver}"></property>
<property name="url" value="${jdbc.url}"></property>
<property name="username" value="${jdbc.name}"></property>

</beans>

（5）数据库配置 db.properties
jdbc.driver=oracle.jdbc.OracleDriver
jdbc.url=jdbc\:oracle\:thin\:@localhost\:1521\:xe
jdbc.name=hr
jdbc.pass=hr

2.4 Service实现

（1）Service接口

public interface FClientService {

//根据id查询用户信息
FClient findClientById(int id) throws Exception;
//获得所有用户信息
List<FClient> findClientList() throws Exception;
//更新新客户信息
String updateClientIfo(FClient fc) throws Exception;
//删除客户信息
String deleteClientIfo(int id) throws Exception;
//新增客户信息
String insertClientIfo(FClient fc) throws Exception;

} （2）Service 接口实现
/**
* 接口实现
* TODO
* 作者：原明卓
* 时间：2016年1月5日上午9:05:20
* 工程：SpringMvcMybatis1Demo
*/
public class FClientServiceImpl implements FClientService{

//Mapper
@Autowired
private FClientMapper fcmapper;

@Override
public FClient findClientById(int id) throws Exception {
return fcmapper.findClientById(id);
}

@Override
public List<FClient> findClientList() throws Exception {
return fcmapper.findClientList();
}

@Override
public String updateClientIfo(FClient fc) throws Exception {
return fcmapper.updateClientIfo(fc)>0?"success":"failed";
}

@Override
public String deleteClientIfo(int id) throws Exception {
return fcmapper.deleteClientIfo(id)>0?"success":"failed";
}

@Override
public String insertClientIfo(FClient fc) throws Exception {
return fcmapper.insertClientIfo(fc)>0?"success":"failed";
}

}

（3）Service 与 Spring 整合：实现ApplicationContext-service.xml
<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-2.5.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-2.5.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-2.5.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-2.5.xsd">
<bean id="fclientService" class="cn.labelnet.ssm.service.impl.FClientServiceImpl"></bean>

（4）Service中使用Spring进行事务控制：ApplicationContext-transcation.xml

<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-2.5.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-2.5.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-2.5.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-2.5.xsd">

<bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager" >
<property name="dataSource" ref="dataSource"></property>
</bean>


<tx:advice id="txManager" transaction-manager="transactionManager">
<tx:attributes>
<tx:method name="insert*" propagation="REQUIRED"/>
<tx:method name="update*" propagation="REQUIRED"/>
<tx:method name="delete*" propagation="REQUIRED"/>
<tx:method name="find*" propagation="SUPPORTS" read-only="true"/>
</tx:attributes>
</tx:advice>


<aop:config>
<aop:pointcut expression="execution(* cn.labelnet.ssm.service.impl.*.*(..))" id="perfrom"/>
<aop:advisor advice-ref="txManager" pointcut-ref="perfrom"/>
</aop:config>

</beans>

2.5 SpringMVC实现

（1）Handler实现

package cn.labelnet.ssm.controller;

import java.util.List;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.servlet.ModelAndView;

import cn.labelnet.ssm.po.FClient;
import cn.labelnet.ssm.service.FClientService;

/**
* TODO 作者：原明卓时间：2016年1月5日下午3:23:11 工程：SpringMvcMybatis1Demo
*/
@Controller
public class FClientController {

@Autowired
private FClientService fcService;

@RequestMapping("/clientslist")
public ModelAndView clientsList(){

ModelAndView view=new ModelAndView();
List<FClient> list;
try {
list = fcService.findClientList();

view.addObject("clients",list);
view.setViewName("clientindex.jsp");
} catch (Exception e) {
view.addObject("error",e.getMessage());
view.setViewName("error.jsp");
}
return view;
}

}

（2）SpringMvc.xml 实现 - 注解实现

<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-2.5.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-2.5.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-2.5.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-2.5.xsd"> 
<!-- 配置Handler:扫描的方式 -->
<context:component-scan base-package="cn.labelnet.ssm.controller"></context:component-scan>

<!-- 注解映射器 -->
<bean class="org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerMapping"></bean>
<!-- 注解适配器 -->
<bean class="org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerAdapter"></bean>

<!-- 使用Mvc：annotation-driven代替上面的注解映射器和适配器
mvc:annotation-driver默认加载很多的参数绑定方法；
那样就不用配置上班的requestMappingHandlerMapping和RequestMappingHandlerAdapter了
推荐使用；<mvc:annotation-driven></mvc:annotation-driven>
-->

<!-- 视图解析器 -->
<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver" />

</beans>

（3）web.xml - SpringMvc 配置, 加载Spring容器
加载Spring容器采用通配符的方式实现，使得可以拓展；


<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>/WEB-INF/classes/spring/applicationContext-*.xml</param-value>
</context-param>
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>


<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>*.action</url-pattern>
</servlet-mapping>

2.6 Jsp页面

</body>
</html>

2.7 测试部署

测试的话，访问Handler中的RequestMapping("") 中的url地址，比如：
http://localhost:8989/SpringMvcMybatis1Demo/clientslist.action

3.总结

首先是Mybatis的实现，在实现的时候，每做一个方法，测试一个方法，以保证正确性；其次在配置SpringMvc和加载Spring容器的时候，采用通配符的方式实现，以保证拓展性；最后，MVC中实现Handler的时候，采用注解的方式，方便开发，一个类中可以写多个方法实现；

在这个例子中，还有很多功能需要完善，比如查询，分页，修改，删除，都是需要实现的；如果类比Asp.net MVC的话，那么Handler的返回值，参数等都需要学习；
