路由配置

      {
        path:'/constantAdd',
        name:'ConstantAdd',
        component:ConstantAdd
    }

后台关键代码

• ConstantTypeController

package com.neuedu.demo.controller;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

import com.neuedu.demo.domain.Constanttype;
import com.neuedu.demo.domain.ResponseBean;
import com.neuedu.demo.service.IConstantTypeService;

@RestController
@RequestMapping("/sys/constanttype")
public class ConstantTypeController {
    @Autowired
    IConstantTypeService constantTypeServiceImpl;
    
    @RequestMapping("add")
    public ResponseBean add(@RequestBody Constanttype type){
        ResponseBean result=new ResponseBean();
        Constanttype db_type=constantTypeServiceImpl.save(type);
        if(db_type!=null){
            result.setCode("0");
            result.setMsg("操作成功");
        }else{
            result.setCode("-1");
            result.setMsg("操作失败");
        }
        return result;
    }

}

• Constanttype实体

  package com.neuedu.demo.domain;

  import java.io.Serializable;
  import javax.persistence.*;

 * 常数类别管理
 */
@Entity

    private String constantTypeName;

    private int delMark=1;
    @GeneratedValue(strategy=GenerationType.IDENTITY)
    @Id
    private int id;

    public Constanttype() {

    public int getId() {
