有没有办法阻止Spring Data REST为重写的存储库方法创建/搜索URL?
例如,以下代码会生成/ search / findAll URL,该URL会复制集合资源的功能:
public interface EmployeeRepository extends CrudRepository<Employee, Long>
{
@Override
@Query("SELECT e FROM Empolyee e")
Iterable<Employee> findAll();
}
这只是覆盖单个方法时的一个美化问题,但如果您尝试使用相同的函数名和不同的参数覆盖多个方法,例如PagingAndSortingRepository中的两个findAll方法,则spring会抛出异常,因为它正在尝试将2个函数映射到同一个路径。
public interface EmployeeRepository extends PagingAndSortingRepository<Employee, Long>
{
@Override
@Query("SELECT e FROM Employee e")
Iterable<Employee> findAll();
@Override
@Query("SELECT e FROM Employee e")
Iterable<Employee> findAll(Sort sort);
@Override
@Query("SELECT e FROM Employee e")
Page<Employee> findAll(Pageable pageable);
}
结果:
java.lang.IllegalStateException: Ambiguous search mapping detected. Both public abstract java.lang.Iterable uk.co.essl.roster.entity.employee.EmployeeRepository.findAll(org.springframework.data.domain.Sort) and public abstract java.lang.Iterable uk.co.essl.roster.entity.employee.EmployeeRepository.findAll() are mapped to /findAll! Tweak configuration to get to unambiguous paths!

我找到了以下技巧来解决这个问题:
@Override
default Page<Employee> findAll(Pageable pageable) {
return findBy(pageable);
}
@RestResource(exported = false)
Page<Employee> findBy(Pageable pageable);
更多其他此技巧允许您设置默认排序顺序以获取所有记录&#39;请求:
@Override
default Page<Employee> findAll(Pageable p) {
if (p.getSort() == null) {
// The default sort order
return findBy(new PageRequest(p.getPageNumber(), p.getPageSize(), Sort.Direction.DESC, "myField"));
}
return findBy(pageable);
}
享受! ))
@RestResource(exported=false)
仅用于重写方法无效,导致此阻止 GET &#39;所有记录&#39;请求(
