主要功能：实现登陆拦截，然后进入主页面进行增删改查工作，开启Druid数据源，进行durid日志监控
编写登陆拦截：创建LoginHandlerInterceptor类
配置开启durid数据源监控功能：创建DruidConfig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)
开启服务，浏览器访问:http://localhost:8080/

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

@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;

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);
到这里就大公告成了，哈哈哈
