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="20880" />
<!-- 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>
</head>
<body>
<h1>登录成功,NB!</h1>
</body>

<div>
<button type="submit" class="btn btn-success">登 录</button>

</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>
<param-value>classpath*:applicationContext.xml</param-value>
</init-param>
</servlet>
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</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-8</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="20880" />
<!-- 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);
}
