3.注解config配置

1.EncodingFilter页面，用于解决代码乱码

package com.config;

import javax.servlet.*;
import javax.servlet.annotation.WebFilter;
import java.io.IOException;

@WebFilter(filterName = "encodingFilter",urlPatterns = "
        @Value("${jdbc.driverClassName}")
        private String driver;
        @Value("${jdbc.url}")
        private String url;
        @Value("${mysql.username}")
        private String username;
        @Value("${jdbc.password}")
        private String password;

        @Bean("dataSource")
        public  DataSource getDataSource() {
            DruidDataSource ds = new DruidDataSource();
            ds.setDriverClassName(driver);
            ds.setUrl(url);
            ds.setUsername(username);
            ds.setPassword(password);
            return ds;
        }
    }

3.MyBatisConfig页面，用于配置Mybatis相关

import org.mybatis.spring.mapper.MapperScannerConfigurer;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Bean;

import javax.sql.DataSource;
import java.util.Properties;

public class MyBatisConfig {
    
    @Bean
    public PageInterceptor getPageInterceptor() {
        PageInterceptor pageInterceptor = new PageInterceptor();
        Properties properties = new Properties();
        properties.setProperty("value","true");
        pageInterceptor.setProperties(properties);
        return pageInterceptor;
    }
    
    @Bean
    public SqlSessionFactoryBean getSqlSessionFactoryBean(
            @Autowired DataSource dataSource,
            @Autowired PageInterceptor pageInterceptor) {
        SqlSessionFactoryBean ssfb =new SqlSessionFactoryBean();
        ssfb.setDataSource(dataSource);
        Interceptor [] plugins =  {pageInterceptor};
        ssfb.setPlugins(plugins);
        return ssfb;
    }
    
    @Bean
    public MapperScannerConfigurer getMapperScannerConfigurer() {
        MapperScannerConfigurer msc = new MapperScannerConfigurer();
        msc.setBasePackage("com.mapper");
        return msc;
    }
}

4.ServletContainersInitConfig页面，用于配置Servlet服务层

package com.config;

import org.springframework.web.servlet.support.AbstractAnnotationConfigDispatcherServletInitializer;

public class ServletContainersInitConfig extends
        AbstractAnnotationConfigDispatcherServletInitializer {
    
    protected Class[] getRootConfigClasses() {
        return new Class[]{com.config.SpringConfig.class};
    }
    
        protected Class[] getServletConfigClasses () {
            return new Class[]{com.config.SpringMvcConfig.class};
        }
        
            protected String[] getServletMappings () {
                return new String[]{"/"};
            }
        }

5.SpringConfig页面，

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.Import;
import org.springframework.jdbc.datasource.DataSourceTransactionManager;
import org.springframework.transaction.annotation.EnableTransactionManagement;

import javax.sql.DataSource;

@Configuration

@Import({com.config.MyBatisConfig.class,JdbcConfig.class})

@ComponentScan("com.service")
@EnableTransactionManagement
public class SpringConfig {
    @Bean("transactionManager")
    public DataSourceTransactionManager getDataSourceTxManager(@Autowired DataSource dataSource){
        DataSourceTransactionManager dtm =new DataSourceTransactionManager();
        dtm.setDataSource(dataSource);
        return dtm;
    }
}

6.SpringMvcConfig页面，用于开启静态资源

package com.config;

import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.config.annotation.*;


@Configuration
@ComponentScan({"com.controller"})
@EnableWebMvc
public class SpringMvcConfig implements WebMvcConfigurer {
    
    @Override
    public void configureDefaultServletHandling(
            DefaultServletHandlerConfigurer configurer) {
        configurer.enable();
    }

三、修改用户信息

1.类

package com.pojo;

import java.util.List;

public class Users {

        private Integer id;
        private String name;
        private String sex;

                this.sex = sex;
        }

        public String getGender() {
                return gender;
        }

        public void setGender(String gender) {
                this.gender = gender;
        }

        public String getAge() {
                return age;

        }

        public void setEmail(String email) {
                this.email = email;
        }

        @Override
        public String toString() {
                return "Users{" +
                        "id=" + id +

                        ", email='" + email + ''' +
                        '}';
        }
}

2.controller层

//修改
    @RequestMapping("/editUsers")
    public ModelAndView editUsers(Users users) {
        ModelAndView modelAndView = new ModelAndView();
        Integer integer = usersService.editUsers(users);
        if (integer==0) {
            modelAndView.setViewName("editUsers");
            modelAndView.addObject("msg","修改失败");

        }
        ModelAndView modelAndView1 = selectUsers();
        modelAndView.addObject("msg","修改成功");
        return modelAndView1;
    }

package com.service;
import com.entity.PageResult;
import com.pojo.Users;
public interface UsersService {

    PageResult findAllUsers(Integer PageNumber, Integer PageSize);

    }

    //删除用户信息
    @Override
    public Integer deleteUsers(Integer id) {
        return usersMapper.deleteUsers(id);
    }
}

四、删除用户

1.类

package com.pojo;

import java.util.List;

public class Users {

        private Integer id;
        private String name;
        private String sex;
        private String gender;
        private String age;
        private String qq;
        private String email;
        private List rows;

        public List getRows() {
                return rows;
        }

        public void setRows(List rows) {
                this.rows = rows;
        }

        public Integer getId() {
                return id;
        }

        public void setId(Integer id) {
                this.id = id;
        }

        public String getName() {
                return name;
        }

        public void setName(String name) {
                this.name = name;
        }

        public String getSex() {
                return sex;
        }

        public void setSex(String sex) {
                this.sex = sex;
        }

        public String getGender() {
                return gender;
        }

        public void setGender(String gender) {
                this.gender = gender;
        }

        public String getAge() {
                return age;
        }

        public void setAge(String age) {
                this.age = age;
        }

        public String getQq() {
                return qq;
        }

        public void setQq(String qq) {
                this.qq = qq;
        }

        public String getEmail() {
                return email;
        }

        public void setEmail(String email) {
                this.email = email;
        }

        @Override
        public String toString() {
                return "Users{" +
                        "id=" + id +
                        ", name='" + name + ''' +
                        ", sex='" + sex + ''' +
                        ", gender='" + gender + ''' +
                        ", age='" + age + ''' +
                        ", qq='" + qq + ''' +
                        ", email='" + email + ''' +
                        '}';
        }
}

2.controller层

//删除
    @RequestMapping("/deleteUsers/{id}")
    public String deleteUsers(@PathVariable("id") Integer id){
        System.out.println(id);
        Integer count = usersService.deleteUsers(id);
        if (count == 0) {
            System.out.println("失败");
        } else {
            System.out.println("成功");
        }
        return "redirect:/users/selectUsers";
    }

3.serlver层

package com.service;
import com.entity.PageResult;
import com.pojo.Users;
public interface UsersService {

    PageResult findAllUsers(Integer PageNumber, Integer PageSize);

    //根据用户名和邮箱查询人物信息
    PageResult findUsers(Users users,Integer pageNumber,Integer pageSize);

    //新增用户信息
    Integer addUsers(Users users);

    //修改用户信息
    Integer editUsers(Users users);

    //删除用户信息
    Integer deleteUsers(Integer id);



}

4.Mapper层

package com.service.impl;
import com.entity.PageResult;
import com.github.pagehelper.Page;
import com.github.pagehelper.PageHelper;
import com.mapper.UsersMapper;
import com.pojo.Users;
import com.service.UsersService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;


@Service
public class UsersServiceImpl implements UsersService {
    @Autowired
    private UsersMapper usersMapper;

    //页面用户显示
    @Override
    public PageResult findAllUsers(Integer pageNumber,Integer pageSize) {
        PageHelper.startPage(pageNumber, pageSize);
        Page page = usersMapper.findAllUsers();
        return new PageResult(page.getTotal(), page.getResult());
    }

    //查询用户
    @Override
    public PageResult findUsers(Users users,Integer pageNumber,Integer pageSize) {
        PageHelper.startPage(pageNumber, pageSize);
        Page page = usersMapper.findUsers(users);
        return new PageResult(page.getTotal(), page.getResult());
    }

    //添加新用户
    @Override
    public Integer addUsers(Users users) {
        return usersMapper.addUsers(users);
    }

    //修改用户信息
    @Override
    public Integer editUsers(Users users){
        return usersMapper.editUsers(users);
    }

    //删除用户信息
    @Override
    public Integer deleteUsers(Integer id) {
        return usersMapper.deleteUsers(id);
    }
}

五、分页插件

这个分页插件很重要，没有的话就无法在用户管理页面看到从数据库传输上来的用户信息

1.类

package com.pojo;


import java.util.List;

public class PageBean {
        private int totalCount;   //总记录数
        private int totalPage; //总页码
        private List list;  //每页中的数据
        private int currentPage;  //当前页码
        private int rows;   //每页的记录数

        public int getTotalCount() {return totalCount;}

        public void setTotalCount(int totalCount) {this.totalCount = totalCount;}

        public int getTotalPage() {return totalPage;}

        public void setTotalPage(int totalPage) {this.totalPage = totalPage;}

        public List getList() {return list;}

        public void setList(List list) {this.list = list;}

        public int getCurrentPage() {return currentPage;}

        public void setCurrentPage(int currentPage) {this.currentPage = currentPage;}

        public int getRows() {return rows;}

        public void setRows(int rows) {this.rows = rows;}
    }

2.方法控制层

package com.controller;

import com.pojo.User;
import com.pojo.Users;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.servlet.ModelAndView;

import javax.servlet.http.HttpSession;

@Controller
public class pageController {
    @RequestMapping("/addView")
    public String addView(){
        return "addView";
    }

    @RequestMapping("/editUsers")
    public ModelAndView editUsers(Users users){
        ModelAndView modelAndView = new ModelAndView();
        modelAndView.setViewName("editUsers");
        modelAndView.addObject("users",users);
        return modelAndView;
    }

    //注销
    @RequestMapping("/logout")
    public String logout(HttpSession session) {
        session.invalidate();
        return "login";
    }
}
