Spring 数据 REST - 覆盖存储库 findAll 而不创建 /search/findAll URL

Question

有什么方法可以防止 Spring Data REST 为覆盖的存储库方法创建 /search URLs？

例如，以下代码导致生成 /search/findAll URL，它复制了集合资源的功能：

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表面问题，但如果您尝试覆盖具有相同函数名称和不同参数的多个方法，例如 PagingAndSortingRepository 中的两个 findAll 方法，那么 spring 会抛出异常，因为它试图将 2 个函数映射到同一路径。

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!

Answer 1

@RestResource(exported = false)

Answer 2

Is there any way to prevent Spring Data REST from creating a /search URLs for overridden repository methods?

我发现以下技巧可以解决这个问题：

@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为 'get all records' 请求设置默认排序顺序：

@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);
}

尽情享受吧！ ))

@RestResource(exported=false) 仅用于覆盖方法将无济于事，因为这会阻止 GET 'all records' 请求（
