本文介绍了一个基于RESTful风格的部门管理API设计实现，包括增删改查等核心功能，并使用MyBatis进行数据库操作。

Controller

package com.gameplay.org.controller;

import com.gameplay.basic.util.AjaxResult;
import com.gameplay.basic.util.PageList;
import com.gameplay.org.aop.LogAop;
import com.gameplay.org.domain.Department;
import com.gameplay.org.service.IDepartmentService;
import com.gameplay.query.DepartmentQuery;
import io.swagger.annotations.ApiOperation;
import io.swagger.annotations.ApiParam;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.*;

import java.util.List;

@RestController
@RequestMapping("/dept")
public class DepartmentController {

    @Autowired
    private IDepartmentService iDepartmentServicee;


/*
    //之前定义方法的方式
    @RequestMapping(value = "/findById",method = RequestMethod.GET)
    public Department findById(Long id) {
        return iDepartmentServicee.findById(id);
    }
    */


    //Restful风格定义
    //路径：heep://localhost:80/dept/1
    @GetMapping("/{id}")
    @ApiOperation(value = "通过ID查询详情" )
    public Department findById(@ApiParam(value="部门id",required = true) @PathVariable("id") Long id){
        return iDepartmentServicee.findById(id);
    }

    //查询全部用户
    @LogAop(name = "查询全部用户",sex = false)
    @GetMapping()
    public List<Department> findAll() {
        return iDepartmentServicee.findAll();
    }

    //添加或修改
    @LogAop(name = "添加或者修改",sex = false)
    @PutMapping()
    public AjaxResult addOrUpdate(@RequestBody Department department) {
        try {
            if (null != department.getId()) {
                //修改
                iDepartmentServicee.update(department);
            }else {
                //添加
                iDepartmentServicee.add(department);
            }
        }catch (Exception e){
            e.printStackTrace();
            return AjaxResult.me().fail();
        }
        return AjaxResult.me().success();
    }


    //删除
    @LogAop(name = "删除",sex = false)
    @DeleteMapping("/{id}")
    public AjaxResult delete(@PathVariable("id") Long id) {
        iDepartmentServicee.delete(id);
        return AjaxResult.me().success();
    }

    @PatchMapping()
    public AjaxResult batchDelete(@RequestBody List<Long> ids){
        iDepartmentServicee.batchDelete(ids);
        return AjaxResult.me().success();
    }


    //分页查询
    @PostMapping()
    public PageList<Department> queryByPage(@RequestBody DepartmentQuery departmentQuery) {
        return iDepartmentServicee.queryByPage(departmentQuery);
    }

    //无限极数
    @GetMapping("/tree")
    private List<Department> tree(){
        return iDepartmentServicee.tree();
    }
}

basic/util的Ajax返回和分页

Ajax返回

package com.gameplay.basic.util;

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

@Data
@AllArgsConstructor
@NoArgsConstructor
public class AjaxResult {
    private Boolean success;
    private String msg;

    public AjaxResult success(){
        return AjaxResult.me().setSuccess(true).setMsg("操作成功");
    }

    public AjaxResult fail(){
        return AjaxResult.me().setSuccess(false).setMsg("操作失败");
    }

    public AjaxResult fail(String msg){
        return AjaxResult.me().setSuccess(false).setMsg(msg);
    }

    public static AjaxResult me(){
        return new AjaxResult();
    }

    public AjaxResult setSuccess(Boolean success) {
        this.success = success;
        return this;
    }

    public AjaxResult setMsg(String msg) {
        this.msg = msg;
        return this;
    }
}

分页

package com.gameplay.basic.util;

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

import java.util.List;


@Data
@AllArgsConstructor
@NoArgsConstructor
public class PageList<T> {

    private Integer totals;
    // vue取值 result.data.rows
    // null []
    private List<T> rows;
}

query文件夹的分页

package com.gameplay.query;


import com.gameplay.basic.query.BaseQuery;
import lombok.Data;

@Data
public class DepartmentQuery extends BaseQuery {
    //关键字
    private String keyword;
    private Integer currentPage = 1;

    private Integer pageSize = 5;

    public Integer getStart(){
        return (currentPage - 1) * pageSize;
    }
}

sql
