JPA排序查询new Sort() Intellij红线报错问题

原因

• 在最新的spring-boot（spring-boot-data）版本中通过new 来创建Sort是不可以的
  
• 查看源码，原来是Sort的构造器私有了private；所以不能通过new Sort()的方式来创建Sort对象
  

而是用 Sort.by()

Sort id = by(DESC,"id");//DESC降序，ASC升序；

直接写字段默认升序，Sort源码如下

示例

@GetMapping("/findAll/{username}")
public List<User> findAllByUsername(@PathVariable(value = "username") String username) {

User user = new User();
user.setUsername(username);

ExampleMatcher matching = ExampleMatcher.matching()
.withMatcher("username", ExampleMatcher.GenericPropertyMatcher::startsWith)
.withIgnorePaths("password");

Example<User> example = Example.of(user, matching);

Sort sort = by(DESC,"id");

return userRepository.findAll(example,sort);

}

结果 (localhost:8080/findAll/jpa)

[
{"id":8,"username":"jpa-2","password":"234"},
{"id":7,"username":"jpa-1","password":"123"},
{"id":6,"username":"jpa-dead","password":"123123123123"},
{"id":5,"username":"jpa-result","password":"12345"}
]
