贴代码:
controller:
@RequestMapping(value = "/list", method = RequestMethod.GET)
public Page list(@RequestParam(value = "sort", defaultValue = "create_time") String search,
@RequestParam(value = "limit", defaultValue = "10") Integer limit,
@RequestParam(value = "page", defaultValue = "0") Integer page) {
Sort sort = new Sort(Sort.Direction.DESC, "create_date");
Pageable pageable = new PageRequest(page, limit, sort);
Page pages = messageInfoService.findByStatusNot(EmMessageStatus.DELETE, pageable);
return pages;
}
dao:
Page<MessageInfo> findByStatusNot(EmMessageStatus status, Pageable pageable);
抛出的异常:
org.springframework.data.mapping.PropertyReferenceException: No property create found for type MessageInfo!
at org.springframework.data.mapping.PropertyPath.<init>(PropertyPath.java:77)
at org.springframework.data.mapping.PropertyPath.create(PropertyPath.java:329)
at org.springframework.data.mapping.PropertyPath.create(PropertyPath.java:309)
at org.springframework.data.mapping.PropertyPath.from(PropertyPath.java:272)
at org.springframework.data.mapping.PropertyPath.from(PropertyPath.java:243)
解决办法:
排序的字段要写成java对象的属性
将controller中create_date
改为createDate
Sort sort = new Sort(Sort.Direction.DESC, "createDate");
