前言:
而今我们对“js获取iframe所有内容”大概比较关切,同学们都想要剖析一些“js获取iframe所有内容”的相关文章。那么小编同时在网络上网罗了一些对于“js获取iframe所有内容””的相关资讯,希望各位老铁们能喜欢,兄弟们快快来了解一下吧!前面介绍了SpringBoot集成LayUI和前端模板Thymeleaf,今天介绍一下数据列表的实现,线上一个简单的支持查询条件的列表实现。话不多说上代码
上前端界面user.html

这里有个坑
表格渲染列的时候,注意 cols: [[ 不要连着写,尽量换个行,因为集成了Thymeleaf,会把 [[ 作为特殊符号LayUI列表页请求结构
// 忽略getset方法public class PageReq { // 返回数据量 public int limit; // 页数 public int page; // 排序字段 private String orderField; // 排序 private String orderBy; @JsonIgnore public int getOffset() { if (page == 0) { return 0; } int tmp = (page - 1) * limit; return tmp < 0 ? 0 : tmp; }}需要分页的请求参数
// 忽略getset方法public class SysUserParam extends PageReq{ private Long userId; /** * 邮箱 */ private String email; /** * 用户状态 */ private String userStatus; private String nickNameFullLike;}LayUI列表页统一返回结构
// 忽略getset方法 public class Response<T> implements Serializable { //错误信息 private String msg; //错误码 0 成功 -1024 失败 private Integer code; // 返回数据 private T data; // 返回数据量 private Integer count; public static <T> Response buildSuccess() { return new Response("", 0, null, null); } public static <T> Response buildFail() { return new Response("", -1024, null, null); } public static <T> Response buildFail(String msg) { return new Response(msg, -1024, null, null); } public static <T> Response buildSuccess(T data, Integer count) { return new Response("", 0, data, count); } public Response(String msg, Integer code, T date, Integer count) { this.msg = msg; this.code = code; this.data = date; this.count = count; } }Controller代码
@RestController@RequestMapping("/sysUser")public class UserController { private Logger logger = LoggerFactory.getLogger(UserController.class); @Resource private SysUserBiz sysUserBiz; /** * 根据主键查询系统用户 */ @PostMapping("/list") public Response<List<SysUserVO>> queryByParam(@RequestBody SysUserParam sysUserParam){ try { return sysUserBiz.selectByCondition(sysUserParam.adaptor()); }catch (Exception e){ logger.error("queryUserList Exception",e); return Response.buildFail(); } }}
后面的底层SQL就忽略了,主要是看前端和controller的交互,以及参数返回值的约定
看下实现效果
总感觉有点水,下次努力
