Spring3 + Spring MVC+ Mybatis 3+Mysql 項目整合（註解及源碼）

Spring3 + Spring MVC+ Mybatis 3+Mysql 項目整合（註解及源碼）

備註：

以前在Spring3 + Spring MVC+ Mybatis 3+Mysql 項目整合中寫到的框架只是用於測試使用，隔了一段時間以後回頭看看，發現有許多須要改進的地方，最近項目中恰好用到，再次補充下！

1.項目目錄：

2.須要的jar包列表：

3.spring bean 配置文件applicationContext.xml

5.spring mvc配置文件springmvc-dispatcher.xml：

<?xml version="1.0" encoding="UTF-8"?>
<beans default-lazy-init="true"

    xmlns:p="http://www.springframework.org/schema/p"

    <!-- 經過註解，把URL映射到Controller上，該標籤默認註冊DefaultAnnotationHandlerMapping和AnnotationMethodHandlerAdapter -->
    <mvc:annotation-driven />

    <bean id="handlerMapping" class="org.springframework.web.servlet.mvc.annotation.DefaultAnnotationHandlerMapping" />

    <!-- 探測註解的包，包括子集， 在JUnit測試的時候須要 --> <!-- 自動掃描bean，把做了註解的類轉換爲bean --> 
    <context:component-scan base-package="com.sgl" />
   <!-- 加載組裝因此配置文件 context:component-scan註冊後能夠省略當前配置
    <context:annotation-config/>
    -->

靜態資源文件訪問條件
    <mvc:default-servlet-handler/>
     
    <!-- 視圖解析器 -->
    <bean id="viewResolver"
        class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <!-- 使用JSP頁面進行輸出 -->

        class="org.springframework.web.multipart.commons.CommonsMultipartResolver" p:defaultEncoding="UTF-8" />
        
        
此處可配置自定義攔截器 
 <!--  <mvc:interceptors>
        <mvc:interceptor>
            <mvc:mapping path="/*/**" />
            <mvc:exclude-mapping path="/cms/login.jsp"/>

        </mvc:interceptor>
    </mvc:interceptors>      -->      
</beans>

6.mybatis配置文件：

    <mappers>  
        <mapper resource="com/sgl/mapping/ManagerInfo.xml" />

8.控制器：

@Controller
@RequestMapping("/manager") public class ManagerAction { private final static String className = ManagerAction.class.getName(); /*可以使用@Resource替代@Autowired 例如：@Resource(name = "managerServiceImpl")*/ @Autowired private ManagerService managerService; @RequestMapping("/login") public String checkLogin(ModelAndView model) { ManagerInfo managerInfo=managerService.checkLogin("shupao"); System.out.println(managerInfo.getManagerName()); model.setViewName("index"); LogUtil.businessInfo(className, "manager "+managerInfo.getManagerName()+"login success"); return "index"; } }

service:

/*@Service(value = "managerService")*/
public interface ManagerService {
 public ManagerInfo checkLogin(String name);
}

 

serviceImpl:

/*@Repository(value = "managerServiceImpl")*/
@Service(value = "managerService")
public class ManagerServiceImpl implements ManagerService {
    @Resource(name = "managerMapper")
    private ManagerMapper managerMapper;
    public ManagerInfo checkLogin(String name) {
        // TODO Auto-generated method stub
        return managerMapper.checkLogin(name);
    }

}

mapper:

@Repository(value = "managerMapper")  
@Transactional 
public interface ManagerMapper{
    public ManagerInfo checkLogin(String name);
}

mapping:

<?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="com.sgl.mapper.ManagerMapper">
<sql id="all_column">
        id id,
        manager_code managerCode,
        manager_name managerName,
        status status,
        remarks remarks,
        deleted deleted,
        create_time createTime,

        password password
    </sql>
    <select id="checkLogin" parameterType="String" resultType="com.sgl.model.ManagerInfo">
        select <include refid="all_column" />
         from t_manager_info where manager_name=#{name,jdbcType=VARCHAR}
    </select>
</mapper>

 總結

知識只有在用的時候才能變得活起來！與上篇文章相比，本次程序搭建的過程更加細緻，考慮的東西也更加全面。不過還有許多須要探索的地方，還得加油！
