一、Consumer子类

MyController类

@Controller

@RequestMapping("/login")

public class MyController {

    @Resource

    private UserService userService;

    @RequestMapping("/checkLogin")

    public String checkLogin(Users users){

        Users users1 = userService.checkLogin(users);

        if (users1==null) {

            return "login";

        }

        return  "index";

    }

}

applicationContext.xml

<mvc:annotation-driven/>

    <context:annotation-config/>

    <!-- 配置视图解析器,设置前缀和后缀，自动拼接 -->

    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">

        <!-- 前缀 -->

        <property name="prefix" value="/jsp/" />

        <!-- 后缀 -->

        <property name="suffix" value=".jsp" />

    </bean>

    <mvc:default-servlet-handler/>

    <!-- 提供方应用信息，用于计算依赖关系 -->

    <dubbo:application name="consumer"/>

    <!-- 使用zookeeper注册中心暴露服务地址 -->

    <dubbo:registry address="192.168.118.3:2181,192.168.118.4:2181,192.168.118.5:2181"   protocol="zookeeper" />

    <!-- 用dubbo协议在20880端口暴露服务 -->

    <dubbo:protocol name="dubbo" port="" />

    <!-- 生成远程服务代理，可以和本地bean一样使用demoService -->

    <dubbo:reference id="userService" interface="com.yjc.service.UserService" />

index.jsp

<%@ page contentType="text/html;charset=UTF-8" language="java" %>

<html>

<head>

    <title>Title</title>

<body>

<h1>登录成功,NB!</h1>

login.jsp

<%@ page language="java" contentType="text/html; charset=UTF-8"

         pageEncoding="UTF-8" isELIgnored="false" %>

        <button type="reset" class="btn btn-default">重　填</button>

    </div>

</form>

web.xml

  <!--Spring和MyBatis整合的核心配置-->

  <context-param>

    <param-name>contextConfigLocation</param-name>

    <param-value>classpath:applicationContext.xml</param-value>

  </context-param>

  <!--配置SpringMVC的核心控制器DispatcherServlet-->

  <servlet>

    <servlet-name>SpringMVC</servlet-name>

    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>

    <init-param>

      <param-name>contextConfigLocation</param-name>

  </listener>

  <servlet-mapping>

    <servlet-name>SpringMVC</servlet-name>

    <!--设置映射路径，/代表所有的请求都会被核心控制器映射到对应的Controller中-->

    <url-pattern>/</url-pattern>

  </servlet-mapping>

  <!--编码过滤器-->

  <filter>

    <filter-name>characterEncodingFilter</filter-name>

    <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>

    <!--初始化参数-->

    <init-param>

      <param-name>encoding</param-name>

      <param-value>UTF-</param-value>

    </init-param>

  </filter>

二、Producers子类

dao层Login类

@Repository

public interface Login {

    @Select("select * from myuser where username=#{userName}")

    Users checkLogin(String userName);

}

impl层UserServiceImpl类

@Service("userService")

public class UserServiceImpl implements UserService {

    @Resource

    private Login login;

    @Override

    public Users checkLogin(Users users) {

        Users users1 = login.checkLogin(users.getUserName());

        if (users1!=null){

            if (users1.getPassword().equals(users.getPassword())){

                return  users1;

            }

        }

        return null;

    }

}

applicationContext.xml

<!--    导入数据库连接文件-->

    <bean class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">

        <property name="ignoreUnresolvablePlaceholders" value="true" />

        <property name="location" value="classpath:jdbc.properties"/>

    </bean>

    <!--配置数据源-->

    <bean  id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource">

        <property name="driverClassName" value="${jdbc.driver}"/>

        <property name="url" value="${jdbc.url}"/>

        <property name="password" value="${jdbc.password}"/>

        <property name="username" value="${jdbc.user}"/>

    </bean>

    <!--配置MyBatis的核心对象SqlSessionFactoryBean-->

    <bean id="SessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">

        <property name="dataSource" ref="dataSource"/>

    </bean>

    <!--创建包扫描器（借助dao接口实现动态代理）-->

    <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer           ">

        <property name="basePackage" value="com.yjc.dao"/>

    </bean>

    <context:component-scan base-package="com.yjc"/>

    <context:annotation-config/>

    <mvc:annotation-driven/>

    <!-- 提供方应用信息，用于计算依赖关系 -->

    <dubbo:application name="app-provider"/>

    <!-- 使用zookeeper注册中心暴露服务地址 -->

    <dubbo:registry address="192.168.118.3:2181,192.168.118.4:2181,192.168.118.5:2181"   protocol="zookeeper" />

    <!-- 用dubbo协议在20880端口暴露服务 -->

    <dubbo:protocol name="dubbo" port="" />

    <!-- 声明需要暴露的服务接口 -->

    <dubbo:service interface="com.yjc.service.UserService" ref="userService" />

三、Service子类

entity包下的Userl类

public class Users implements Serializable {

    private Integer id;

    private  String userName;

    private  String password;

    public Integer getId() {

        return id;

    }

    public void setId(Integer id) {

        this.id = id;

    }

    public String getUserName() {

        return userName;

    }

    public void setUserName(String userName) {

        this.userName = userName;

    }

    public String getPassword() {

        return password;

    }

    public void setPassword(String password) {

        this.password = password;

    }

    @Override

    public String toString() {

        return "Users{" +

                "id=" + id +

                ", userName='" + userName + '\'' +

                ", password='" + password + '\'' +

                '}';

    }

    public Users() {

    }

    public Users(Integer id, String userName, String password) {

        this.id = id;

        this.userName = userName;

        this.password = password;

    }

}

service包下的UserService

public interface UserService {

    Users checkLogin(Users users);

}
