Question

如何使用Spring Data Rest删除实体？

这是我的存储库：

package br.com.qrbibliokode.repositories;

import org.springframework.data.repository.CrudRepository;
import org.springframework.data.repository.query.Param;
import org.springframework.data.rest.core.annotation.RepositoryRestResource;

import br.com.qrbibliokode.entities.LivroEntity;

    @RepositoryRestResource(collectionResourceRel = "livro", path = "livro")
    public interface LivroRepository extends CrudRepository<LivroEntity, Long> {

        LivroEntity findById(@Param("id") Long id);

        LivroEntity findByTitulo(@Param("titulo") String titulo);

        @Override
        public void delete(Long id);

        @Override
        public void delete(LivroEntity id);

    }

这是服务器：http://felansu.sytes.net:8080/qr-bibliokode-ws/livro/

我尝试发送删除请求（Whit Advanced Rest Client chrome-extension），但这是返回：

这解决了我的问题。

我用@RestController注释创建了LivroController。

@RestController
public class LivroController {

@Autowired
LivroRepository livroRepository;

@RequestMapping(value = "/livroInserir", method = RequestMethod.POST, consumes = "application/json")
public @ResponseBody LivroEntity inserir(@RequestBody LivroEntity livro) {
    return livroRepository.save(livro);
}

@RequestMapping(value = "/livroDeletarById", method = RequestMethod.DELETE)
public @ResponseBody void deletarById(@RequestParam(value="id") Long id) {
    livroRepository.delete(livroRepository.findById(id));
}

@RequestMapping(value = "/livroDeletarByTitulo", method = RequestMethod.DELETE)
public @ResponseBody void deletarByTitulo(@RequestParam(value="titulo") String titulo) {
    livroRepository.delete(livroRepository.findByTitulo(titulo));
}

@RequestMapping(value = "/livroProcurarById", method = RequestMethod.GET)
public LivroEntity procurarById(@RequestParam(value="id") Long id) {
    return livroRepository.findById(id);
}

@RequestMapping(value = "/livroProcurarByTitulo", method = RequestMethod.GET)
public LivroEntity procurarByTitulo(@RequestParam(value="titulo") String titulo) {
    return livroRepository.findByTitulo(titulo);
}

@RequestMapping(value = "/livroListarTodos", method = RequestMethod.GET)
public ArrayList<LivroEntity> listarTodos() {
    return (ArrayList<LivroEntity>) livroRepository.findAll();
}

@RequestMapping(value = "/livroAtualizar", method = RequestMethod.PUT, consumes = "application/json")
public LivroEntity atualizar(@RequestBody LivroEntity livro) {
    LivroEntity editado = livroRepository.findOne(livro.getId());
    editado.setTitulo(livro.getTitulo());
    return livroRepository.save(editado);
}

并使用以下语法：

Inserir livro via Post： http：// localhost：8080 / qr-bibliokode-ws / inserir {“id”：“1”，“titulo”：“Nome do livro”}

Deletar por id via DELETE http：// localhost：8080 / qr-bibliokode-ws / livroDeletarById？id = 1

Deletar por titulo通过DELETE http：// localhost：8080 / qr-bibliokode-ws / livroDeletarByTitulo？titulo = John

通过GET进行检索 http：// localhost：8080 / qr-bibliokode-ws / livroProcurarById？id = 1

通过GET检索titulo http：// localhost：8080 / qr-bibliokode-ws / livroProcurarByTitulo？titulo = Johns

Listar todos os livros通过GET http：// localhost：8080 / qr-bibliokode-ws / livroListarTodos

Atualizar livro通过PUT http：// localhost：8080 / qr-bibliokode-ws / livroAtualizar {“id”：“1”，“titulo”：“Novo titulo”}
