常见的HTTP请求格式 　　

　　　　PUT、GET

　　　　但其实还有两种请求格式 ：DELETE、POST

未使用restful

http://127.0.0.1/user/query/1 GET 根据用户id查询用户数据
http://127.0.0.1/user/save POST 新增用户
http://127.0.0.1/user/update POST 修改用户信息
http://127.0.0.1/user/delete/1 GET/POST 删除用户信息

使用restful http://127.0.0.1/user/1  GET根据用户id查询用户数据 http://127.0.0.1/user      POST 新增用户 http://127.0.0.1/user     PUT 修改用户信息 http://127.0.0.1/user   DELETE 删除用户信息     　　　　　　（其中@RequestHeader)表示在请求头中 对应Headers，（@RequestParam）对应Params  （@RequestBody）对应Body 　　

@GetMapping(path = "items", name = "查询字典项")
public List<DictItem> queryItem(@RequestHeader(name = "pageNo", defaultValue = "1") Integer pageNo,
                                @RequestHeader(name = "pageSize", defaultValue = "15") Integer pageSize,
                                @RequestParam(name = "dictId") String dictId,
                                @RequestParam(name = "codeOrName", required = false) String codeOrName,
                                @RequestParam(name = "sort", defaultValue = "seq", required = false) String sort,
                                @RequestParam(name = "asc", defaultValue = "true", required = false) boolean asc) {

    log.info("查询字典项列表");

    EntityWrapper<DictItem> ew = new EntityWrapper<>();

    ew.eq("c_dict_id",dictId);

    if (!StringUtils.isEmpty(codeOrName)) {
        ew.andNew();
        ew.like("c_code", codeOrName);
        ew.or();
        ew.like("c_name", codeOrName);
    }
    ew.orderBy(cols.get(sort), asc);

    Page<DictItem> page = new Page<>(pageNo, pageSize);
    page = itemService.selectPage(page, ew);

    log.info("总数：{}", page.getTotal());
    response.setIntHeader(CommonConst.RECORD_TOTAL, (int) page.getTotal());
    return page.getRecords();

}

 

@PostMapping(name = "添加部门")
public String add(@RequestBody Department dept){
    deptService.insert(dept);
    return dept.getId();
}

@PutMapping(path = "{id}", name = "更新字典")
public void update(@PathVariable String id, @RequestBody @Valid Dict dict)  {

    Dict old = dictService.selectById(id);
    log.info("更新字典【{}】", old.getName());
    dictService.updateById(dict);
    // 清缓存
    DictCache.clearDict(old.getCode());
}

@DeleteMapping(path = "items/{itemId}", name = "删除字典项")
public void deleteItem(@PathVariable(name = "itemId") String itemId) {

    itemService.deleteById(itemId);
}



以下为restful返回的数据格式，分为 code，msg，data　　data表示返回的数据
