3 新增权限信息
3.1 controller代码
RoleController.java
package com.cloudtech.controller;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;
import com.cloudtech.dao.RoleMapper;
import com.cloudtech.entity.Role;
/**
* 角色控制器
* @ClassName: RoleController
* @Description:
* @author wude
* @date 2018年12月11日
*
*/
@Controller
@RequestMapping("/role")
public class RoleController {
@Autowired
private RoleMapper roleMapper;
/**
* 方便通过url地址直接访问网站
* @param page
* @return
*/
@RequestMapping("/{page}")
public String page(@PathVariable String page){
return page;
}
/**
* 增加角色信息
* @param role
* @return
*/
@RequestMapping("/addRole")
public String roleIndex(Role role){
int result = roleMapper.insertSelective(role);
if(result > 0){
return "ok";
}else{
return "error";
}
}
}
DemoController.java 控制跳转页面的
package com.cloudtech.controller;
import java.util.ArrayList;
import java.util.Date;
import java.util.HashMap;
import java.util.List;
import java.util.Map;
import javax.servlet.http.HttpServletRequest;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;
import com.cloudtech.entity.User;
@Controller
public class DemoController {
/**
* 方便通过url地址直接访问网站
* @param page
* @return
*/
@RequestMapping("/{page}")
public String page(@PathVariable String page){
return page;
}
}
3.2 dao类
package com.cloudtech.dao;
import com.cloudtech.entity.Role;
import tk.mybatis.mapper.common.Mapper;
public interface RoleMapper extends Mapper<Role>{
}3.3 实体类
package com.cloudtech.entity;
import java.io.Serializable;
import javax.persistence.Column;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
/**
*
* @ClassName: Role
* @Description: 角色
* @author wude
* @date 2018年6月25日
*
*/
public class Role implements Serializable{
/**
*
*/
private static final long serialVersionUID = 1L;
@Id
@Column
@GeneratedValue(strategy = GenerationType.IDENTITY)
/**
* @author wilson
*主键id
*/
private Integer id;
/**
* @author wilson
*角色名称
*/
private String name;
/**
* @author wilson
*角色描述
*/
private String description;
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 == null ? null : name.trim();
}
public String getDescription() {
return description;
}
public void setDescription(String description) {
this.description = description == null ? null : description.trim();
}
@Override
public String toString() {
return "Role [id=" + id + ", name=" + name + ", description=" + description + "]";
}
}记住一定要序列化，使用通用mapper
补一个启动类的代码,启动类一定要这样配置
package com.cloudtech;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.web.servlet.ServletComponentScan;
import tk.mybatis.spring.annotation.MapperScan;
/**
*
* @ClassName: App2
* @Description:
* @author wude
* @date 2018年12月11日
*
*/
@SpringBootApplication
@ServletComponentScan
@MapperScan(basePackages = "com.cloudtech.dao")
public class App2 {
public static void main(String[] args) {
SpringApplication.run(App2.class, args);
}
}
3.4 数据库表结构

点击提交
查看数据库的数据
就这样，添加权限的功能就OK咯。
4 权限列表信息
4.1 controller类

}
}
