java - 查询没有返回唯一结果: 3; nested exception is javax. persistence.NonUniqueResultException:(Spring JPA项目)

Question

我在本地进行了实验，并将spring JPA项目作为jar文件分发到另一台云服务器。然而，云服务器出现错误。原因是什么？

NOTE: I'm not using Resource Server

Oauth2AuthorizationServerConfiguration.java

@Configuration
@EnableAuthorizationServer
public class Oauth2AuthorizationServerConfiguration extends AuthorizationServerConfigurerAdapter {

    @Bean
    public TokenStore tokenStore() {
        return new InMemoryTokenStore();
    }

    @Autowired
    private AuthenticationManager authenticationManager;

    @Autowired
    private PasswordEncoder passwordEncoder;

    @Autowired
    UserDetailsServiceImpl userDetailsServiceImpl;

    @Autowired
    private DataSource datasource;

    @Override
    public void configure(ClientDetailsServiceConfigurer clients) throws Exception {

    clients.inMemory().withClient("testClientId").secret(passwordEncoder.encode("testSecret"))
                .redirectUris("http://11.11.111.111:8080/oauth2/callback")
                .authorizedGrantTypes("authorization_code")
                .scopes("read", "write").accessTokenValiditySeconds(30000);
    }

    @Override
    public void configure(AuthorizationServerEndpointsConfigurer endpoints) throws Exception {
                 endpoints.tokenStore(tokenStore())
        .authenticationManager(authenticationManager)
        .userDetailsService(userDetailsServiceImpl);
    }

    @Override
    public void configure(AuthorizationServerSecurityConfigurer security) throws Exception {
        security.tokenKeyAccess("permitAll()")
                .checkTokenAccess("isAuthenticated()")
                .allowFormAuthenticationForClients();
    }

Controller.java

    @GetMapping(value = "/oauth2/callback")
    public OAuthToken callbackSocial(@RequestParam String code) {

        String credentials = "testClientId:testSecret";
        String encodedCredentials = new String(Base64.encodeBase64(credentials.getBytes()));

        HttpHeaders headers = new HttpHeaders();
        headers.setContentType(MediaType.APPLICATION_FORM_URLENCODED);
        headers.add("Authorization", "Basic " + encodedCredentials);


        MultiValueMap<String, String> params = new LinkedMultiValueMap<>();
        params.add("code", code);
        params.add("grant_type", "authorization_code");
        params.add("redirect_uri", "http://11.11.111.111:8080/oauth2/callback");
        HttpEntity<MultiValueMap<String, String>> request = new HttpEntity<>(params, headers);

        ResponseEntity<String> response = restTemplate.postForEntity("http://11.11.111.111:8080/oauth/token", request, String.class);
        if (response.getStatusCode() == HttpStatus.OK) {
            return gson.fromJson(response.getBody(), OAuthToken.class);
        }
        return null;
    }

调用 api 时出错

http://11.11.111.111:8080/oauth/authorize?client_id=testClientId&redirect_uri=http://11.11.111.111:8080/oauth2/callback&response_type=code&scope=read

似乎存在同一个 api 被多次调用的问题。为什么会出现这种情况？我该如何修复它？

Answer 1

对我来说，堆栈跟踪看起来就像您多次将“testClientId”添加到您尝试访问的 oauth 服务器中:

Caused by: javax.persistence.NonUniqueResultException: query did not return a unique result: 4

您是否将条目直接添加到数据库中？您是否尝试删除这些条目？
