Spring+SpringMVC19_Spring练习-角色管理操作2

一、用户表和角色表的关系

　分析用户和角色在数据库设计中的表关系:多对多关系，关系如图所示：

　

二、角色列表的展示步骤分析

　需求：角色列表展示，需求如图所示：

　

　完成该功能的思路和步骤为：

　　1. 点击角色管理菜单发送请求到服务器端(修改角色管理菜单的url地址)

　　2. 创建RoleController和showList()方法

　　3. 创建RoleService和showList()方法

　　4. 创建RoleDao和findAll()方法

　　5. 使用JdbcTemplate完成查询操作

　　6. 将查询数据存储到Model中

　　7. 转发到role-list.jsp页面进行展示

三、角色列表展示- controller层实现

　1. 修改左侧菜单链接地址：aside.jsp

 

<%@ page language="java" contentType="text/html; charset=UTF-8"
    pageEncoding="UTF-8"%>
<aside class="main-sidebar">
    <!-- sidebar: style can be found in sidebar.less -->
    <section class="sidebar">
        <!-- Sidebar user panel -->
        <div class="user-panel">
            <div class="pull-left image">
                <img src="${pageContext.request.contextPath}/img/user2-160x160.jpg"
                    class="img-circle" alt="User Image">
            </div>
            <div class="pull-left info">
                <p>
                    <security:authentication property="principal.username" />
                </p>
                <a href="#"><i class="fa fa-circle text-success"></i> 在线</a>
            </div>
        </div>

        <!-- sidebar menu: : style can be found in sidebar.less -->
        <ul class="sidebar-menu">
            <li class="header">菜单</li>
            <li id="admin-index"><a
                href="${pageContext.request.contextPath}/pages/main.jsp"><i
                    class="fa fa-dashboard"></i> <span>首页</span></a></li>

            <li class="treeview"><a href="#"> <i class="fa fa-cogs"></i>
                    <span>系统管理</span> <span class="pull-right-container"> <i
                        class="fa fa-angle-left pull-right"></i>
                </span>


            </a>
                <ul class="treeview-menu">

                    <li><a
                        href="${pageContext.request.contextPath}/pages/user-list.jsp"> <i
                            class="fa fa-circle-o"></i> 用户管理
                    </a></li>
                    <li><a
                        <%--href="${pageContext.request.contextPath}/pages/role-list.jsp"> <i--%>
                            href="${pageContext.request.contextPath}/role/list"> <i
                            class="fa fa-circle-o"></i> 角色管理
                    </a></li>
                    <li><a
                        href="${pageContext.request.contextPath}/pages/syslog-list.jsp"> <i
                            class="fa fa-circle-o"></i> 访问日志
                    </a></li>
                </ul></li>
            <li class="treeview"><a href="#"> <i class="fa fa-cube"></i>
                    <span>基础数据</span> <span class="pull-right-container"> <i
                        class="fa fa-angle-left pull-right"></i>
                </span>
            </a>
                <ul class="treeview-menu">

                    <li><a
                        href="#">
                            <i class="fa fa-circle-o"></i> 产品管理
                    </a></li>
                    <li><a
                        href="#">
                            <i class="fa fa-circle-o"></i> 订单管理
                    </a></li>

                </ul></li>

        </ul>
    </section>
    <!-- /.sidebar -->
</aside>

 

　2. Controller层代码：

package com.itheima.controlloer;

import com.itheima.domain.Role;
import com.itheima.service.RoleService;
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 java.util.List;

@RequestMapping("/role")
@Controller
public class RoleController {

    @Autowired
    private RoleService roleService;

    @RequestMapping("/list")
    public ModelAndView list(ModelAndView modelAndView){
        List<Role> roleList =  roleService.list();
        //设置模型
        modelAndView.addObject("roleList",roleList);
        //设置视图
        modelAndView.setViewName("role-list");
        return modelAndView;
    }
}

四、角色列表展示- service和dao层实现

package com.itheima.dao;

import com.itheima.domain.Role;
import java.util.List;

public interface RoleDao {

    public List<Role> findAll();
}
package com.itheima.dao.impl;

import com.itheima.dao.RoleDao;
import com.itheima.domain.Role;
import org.springframework.jdbc.core.BeanPropertyRowMapper;
import org.springframework.jdbc.core.JdbcTemplate;
import java.util.List;

public class RoleDaoImpl implements RoleDao {

    private JdbcTemplate jdbcTemplate;

    public void setJdbcTemplate(JdbcTemplate jdbcTemplate) {
        this.jdbcTemplate = jdbcTemplate;
    }

    public List<Role> findAll() {
        List<Role> roleList = jdbcTemplate.query("select * from sys_role", new BeanPropertyRowMapper<Role>(Role.class));
        return roleList;
    }
}
package com.itheima.service;

import com.itheima.domain.Role;
import java.util.List;

public interface RoleService {

    public List<Role> list();
}
package com.itheima.service.impl;

import com.itheima.dao.RoleDao;
import com.itheima.domain.Role;
import com.itheima.service.RoleService;
import java.util.List;

public class RoleServiceImpl implements RoleService {

    private RoleDao roleDao;

    public void setRoleDao(RoleDao roleDao) {
        this.roleDao = roleDao;
    }

    public List<Role> list(){
        List<Role> roleList = roleDao.findAll();
        return roleList;
    }
}

五、角色列表展示-配置实现

　1. spring-mvc.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"
       xmlns:mvc="http://www.springframework.org/schema/mvc"
       xmlns:context="http://www.springframework.org/schema/context"
       xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
       http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc.xsd
       http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd">
    
    <!-- 1、mvc的注解驱动 -->
    <mvc:annotation-driven/>
    <!--2、配置视图解析器-->
    <bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="prefix" value="/pages/"/>
        <property name="suffix" value=".jsp"/>
    </bean>
    <!-- 3、静态资源权限开放-->
    <mvc:default-servlet-handler />
    <!--4、组件扫描 扫描Controller -->
    <context:component-scan base-package="com.itheima.controlloer"/>
    
</beans>

　2. 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"
       xmlns:context="http://www.springframework.org/schema/context"
       xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
                           http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd">
    
    <context:property-placeholder location="classpath:jdbc.properties"/>

    <bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">
        <property name="driverClass" value="${jdbc.driver}"/>
        <property name="jdbcUrl" value="${jdbc.url}"/>
        <property name="user" value="${jdbc.username}"/>
        <property name="password" value="${jdbc.password}"/>
    </bean>

    <bean id="jdbcTemplate" class="org.springframework.jdbc.core.JdbcTemplate">
        <property name="dataSource" ref="dataSource"/>
    </bean>

    <bean id="roleDao" class="com.itheima.dao.impl.RoleDaoImpl">
        <property name="jdbcTemplate" ref="jdbcTemplate"/>
    </bean>
    <bean id="roleService" class="com.itheima.service.impl.RoleServiceImpl">
        <property name="roleDao" ref="roleDao"/>
    </bean>
</beans>

六、角色列表展示-页面展示

　在role-list.jsp中将数据取出来并展示,核心代码如下： 

<%@ page language="java" contentType="text/html; charset=UTF-8"
    pageEncoding="UTF-8"%>
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>

<html>
<head>
<!-- 页面meta -->
<meta charset="utf-8">

　　启动tomcat添加一个角色，保存发现有乱码

　　　

 　　解决办法：

　　　　为了解决post提交中文乱码问题，需要在web.xml中配置全局乱码过滤器 

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_4_0.xsd"
         version="3.1">

  <!--解决乱码的过滤器-->
  <filter>
    <filter-name>CharacterEncodingFilter</filter-name>
    <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
    <init-param>
      <param-name>encoding</param-name>
      <param-value>UTF-8</param-value>
    </init-param>
  </filter>
  <filter-mapping>
    <filter-name>CharacterEncodingFilter</filter-name>
    <url-pattern>/*</url-pattern>
  </filter-mapping>

  <!-- 全局初始化参数 -->
  <context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>classpath:applicationContext.xml</param-value>
  </context-param>

  <!-- Spring的监听器 -->
  <listener>
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
  </listener>

  <!-- SpringMVC的前端控制器 -->
  <servlet>
    <servlet-name>DispacherServlet</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <init-param>
      <param-name>contextConfigLocation</param-name>
      <param-value>classpath:spring-mvc.xml</param-value>
    </init-param>
    <load-on-startup>1</load-on-startup>
  </servlet>
  <servlet-mapping>
    <servlet-name>DispacherServlet</servlet-name>
    <url-pattern>/</url-pattern>
  </servlet-mapping>

</web-app>
