配置登陆拦截器以及开启durid监控

     配置开启拦截功能: 创建MyMvConfig类           

package com.chen.springbootcruddemo.config;

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.LocaleResolver;
import org.springframework.web.servlet.config.annotation.InterceptorRegistry;
import org.springframework.web.servlet.config.annotation.ViewControllerRegistry;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurer;

@Configuration
public class MyMvConfig implements WebMvcConfigurer 

    @Override
    public void addViewControllers(ViewControllerRegistry registry) 
 //       registry.addViewController("/").setViewName("login");
        registry.addViewController("/login.html").setViewName("login");
//        registry.addViewController("/main.html").setViewName("dashboard");
    

    @Override
    public void addInterceptors(InterceptorRegistry registry) 
        registry.addInterceptor(new LoginHandlerInterceptor()).

   //进行拦截资源             addPathPatterns("/**").excludePathPatterns("/login.html","/","/login","/css/**","/js/**","/img/**");
    

     编写登陆拦截:创建LoginHandlerInterceptor类              

package com.chen.springbootcruddemo.config;

import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.HandlerInterceptor;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;


public class LoginHandlerInterceptor  implements HandlerInterceptor   


    @Override
    public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler) throws Exception 



        //登陆成功之后,应该有用户的session
        Object loginUser=  request.getSession().getAttribute("loginUser");
        if(loginUser==null)
            System.out.println("=================");
            request.setAttribute("msg","没有权限,请先登录");
            request.getRequestDispatcher("/login.html").forward(request,response);
            return  false;
        
        else 
            return true;
        
    



           配置开启durid数据源监控功能:创建DruidConfig类

          开启后:在浏览器打开查看监控:http://localhost:8080/druid/index.html

           登陆 :admin  密码:123456                

package com.chen.springbootcruddemo.config;

import com.alibaba.druid.pool.DruidDataSource;
import com.alibaba.druid.support.http.StatViewServlet;
import com.alibaba.druid.support.http.WebStatFilter;
import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.boot.web.servlet.FilterRegistrationBean;
import org.springframework.boot.web.servlet.ServletRegistrationBean;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

import javax.sql.DataSource;
import java.util.HashMap;
import java.util.Map;

@Configuration
public class DruidConfig 

    @ConfigurationProperties(prefix = "spring.datasource")
    @Bean
    public DataSource druidDataSource()

        return  new DruidDataSource();
    


    //后台监控:web.xml,ServletRegistrationBean
    //因为SpringBoot 内置了servlet容器,所以没有web.xml,替代方法
    //访问:http://localhost:8080/druid
    @Bean
    public ServletRegistrationBean statViewServlet()
        ServletRegistrationBean bean=   new ServletRegistrationBean<>(new StatViewServlet(),"/druid/*");


        //后台需要有人登录,账号密码配置
        HashMap<Object,Object> initParameters=new HashMap<>();
        initParameters.put("loginUsername","admin");//登录key 是固定的loginUserUsername loginPassword
        initParameters.put("loginPassword","123456");

        //允许谁可以访问
        initParameters.put("allow","");
        //禁止谁能访问  initParameters.put("allow","121.0.0.1");

        bean.setInitParameters(initParameters);//设置初始化参数
        return bean;

    

//    //filter
//    @Bean
//    public FilterRegistrationBean webStatFilter()
//
//        FilterRegistrationBean bean=new FilterRegistrationBean();
//
//        bean.setFilter(new WebStatFilter());
//        //可以过滤哪些请求呢?
//        Map<String,String> initParameters=new HashMap<>();
//
//        //这些东西不进行统计
//        initParameters.put("exclusions","*.js,*.css,/druid/*");
//
//        bean.setInitParameters(initParameters);
//
//        return  bean;
//    


 

编写实体类:

 

           创建Message类:     (使用了lombok插件,没有需要安装该插件或者手动生成getter和setter)        

package com.chen.springbootcruddemo.pojo;

import lombok.AllArgsConstructor;
import lombok.Data;
import lombok.NoArgsConstructor;
import org.springframework.beans.factory.annotation.Autowired;

@Data
@AllArgsConstructor
@NoArgsConstructor
public class Message 

    private int id;
    private String content;
    private String title;


 

      创建 User类  

          

package com.chen.springbootcruddemo.pojo;

import lombok.AllArgsConstructor;
import lombok.Data;
import lombok.NoArgsConstructor;

@Data
@AllArgsConstructor
@NoArgsConstructor
public class User 

    private int id;
    private String name;
    private String pwd;



   

编写mapper类

 

      创建MesageMapper类

                 

package com.chen.springbootcruddemo.mapper;

import com.chen.springbootcruddemo.pojo.Message;
import org.apache.ibatis.annotations.Mapper;
import org.springframework.stereotype.Repository;

import java.util.List;
@Mapper
@Repository
public interface MessageMapper 

    List<Message> queryMessage();

    int addMessage(Message message);
    
    int deleteMessage(String id);
    Message queryMessageById(String id);
    int updateMessage(Message message);

    List<Message> queryByMessage(String content);

       创建UserMapper类    

package com.chen.springbootcruddemo.mapper;

import com.chen.springbootcruddemo.pojo.User;
import org.apache.ibatis.annotations.Mapper;
import org.springframework.stereotype.Repository;

@Repository
@Mapper
public interface UserMapper 
    User login(String name);


 

编写mapper映射文件

       

      创建MessageMapper.xml

              

<?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.chen.springbootcruddemo.mapper.MessageMapper">


    <!--id为方法名,resultType为结果返回类型-->
    <select id="queryMessage"  resultType="Message">
    select * from mybatis.show  ;
  </select>


    <!--插入语句,对象中的属性,可以直接取出来-->
    <insert id="addMessage" parameterType="Message" >
          insert into mybatis.show (title,content) values (#title,#content);
      </insert>

    <!--删除用户-->
    <delete id="deleteMessage" parameterType="string">
        delete from mybatis.show where id=#id;
    </delete>

    <!--id为方法名,resultType为结果返回类型-->
    <select id="queryMessageById" parameterType="string" resultType="Message">
    select * from mybatis.show  where  id=#id;
  </select>


    <!--更改用户语句-->
    <update id="updateMessage" parameterType="Message" >
        update mybatis.show set title =#title,content=#content where id=#id;
      </update>


    <!--查询信息-->
    <select id="queryByMessage" parameterType="string" resultType="Message">
        select *  from mybatis.show where content like  concat("%",#content,"%") or title   like concat("%",#content,"%")
    </select>

</mapper>

             创建UserMapper.xml

                             

<?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.chen.springbootcruddemo.mapper.UserMapper">


    <!--select查询语句-->
    <!--id为方法名,resultType为结果返回类型-->
    <select id="login" parameterType="string" resultType="User">

    List<Message> queryMessage();
    int addMessage(Message message);
    int deleteMessage(String id);
    Message queryMessageById(String id);
    int updateMessage(Message message);
    List<Message> queryByMessage(String content);

               创建MessageServiceImpl类              

package com.chen.springbootcruddemo.service;

import com.chen.springbootcruddemo.mapper.MessageMapper;
import com.chen.springbootcruddemo.pojo.Message;
import org.springframework.stereotype.Service;

import javax.annotation.Resource;
import java.util.List;

@Service
public class MessageServiceImpl implements MessageService
    @Resource
    MessageMapper messageMapper;

    @Override
    public List<Message> queryMessage() 
        return messageMapper.queryMessage();
    

    @Override
    public int addMessage(Message message) 
        return messageMapper.addMessage(message);
    

    @Override
    public int deleteMessage(String id) 
        return messageMapper.deleteMessage(id);
    

    @Override
    public Message queryMessageById(String id) 
        return messageMapper.queryMessageById(id);
    

    @Override
    public int updateMessage(Message message) 
        return messageMapper.updateMessage(message);
    

    @Override
    public List<Message> queryByMessage(String content)

哈哈哈,终于到最后了,累呀

 

创建数据库:mybatis

             然后创建数据表

DROP TABLE IF EXISTS `show`;
CREATE TABLE `show`  (
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `content` varchar(255) CHARACTER SET gbk COLLATE gbk_chinese_ci NOT NULL,
  `title` varchar(255) CHARACTER SET gbk COLLATE gbk_chinese_ci NOT NULL,
  PRIMARY KEY (`id`) USING BTREE
) ENGINE = InnoDB AUTO_INCREMENT = 7 CHARACTER SET = gbk COLLATE = gbk_chinese_ci ROW_FORMAT = Compact;


INSERT INTO `show` VALUES (1, '测试测试', '测试');
INSERT INTO `show` VALUES (5, '123456', 'www2222222222');








DROP TABLE IF EXISTS `user`;
CREATE TABLE `user`  (
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `name` varchar(25) CHARACTER SET gbk COLLATE gbk_chinese_ci NULL DEFAULT NULL,
  `pwd` varchar(25) CHARACTER SET gbk COLLATE gbk_chinese_ci NULL DEFAULT NULL,
  `perms` varchar(255) CHARACTER SET gbk COLLATE gbk_chinese_ci NULL DEFAULT NULL,
  PRIMARY KEY (`id`) USING BTREE
) ENGINE = InnoDB AUTO_INCREMENT = 20 CHARACTER SET = gbk COLLATE = gbk_chinese_ci ROW_FORMAT = Compact;



INSERT INTO `user` VALUES (18, 'root', '123456', 'user:update');
INSERT INTO `user` VALUES (19, '123', '123', NULL);
