Spring和DbUnit BeanCreationException Java

Question

我在写一个使用Spring和DBUnit的集成测试，但是我在@Autowired字段中遇到了一些问题。我认为问题来自于这个字段私人WebApplicationContext wac;我搜索这个问题，尝试很多事情但没有成功。

ControllerTest

@RunWith(SpringJUnit4ClassRunner.class) 
@WebAppConfiguration 
@ContextConfiguration(locations = { "classpath:LoginControllerTest2-context.xml" }) 
@TestExecutionListeners({ DependencyInjectionTestExecutionListener.class, DirtiesContextTestExecutionListener.class, 
     TransactionalTestExecutionListener.class, DbUnitTestExecutionListener.class }) 
@DatabaseSetup("login.xml") 
public class LoginControllerTest2 { 

    private static final String JDBC_DRIVER = "org.h2.Driver"; 
    private static final String JDBC_URL = "jdbc:h2:mem:login;DB_CLOSE_DELAY=-1"; 
    private static final String USER = "sa"; 
    private static final String PASS = ""; 
    private static final String SCHEMA_FILE = "h2.sql"; 
    private static final String DATASET = "login.xml"; 

    private MockMvc mockMvc; 

    @Autowired 
    private WebApplicationContext wac; 

    @BeforeClass 
    public static void createSchema() throws ClassNotFoundException { 
     Class.forName(JDBC_DRIVER); 
     try { 
      Connection conn = dataSource().getConnection(); 
      InputStreamReader in = new InputStreamReader(LoginControllerTest2.class.getResourceAsStream(SCHEMA_FILE)); 
      RunScript.execute(conn, in); 
     } catch (Exception e) { 
      // TODO: handle exception 
     } 
    } 

    @Before 
    public void loadTestData() throws Exception { 
     this.mockMvc = MockMvcBuilders.webApplicationContextSetup(this.wac).build(); 
     IDataSet ids = new FlatXmlDataSetBuilder().build(LoginControllerTest2.class.getResourceAsStream(DATASET)); 
     JdbcDatabaseTester databaseTester = new JdbcDatabaseTester(JDBC_DRIVER, JDBC_URL, USER, PASS); 
     databaseTester.setSetUpOperation(org.dbunit.operation.DatabaseOperation.CLEAN_INSERT); 
     databaseTester.setDataSet(ids); 
     databaseTester.onSetup(); 
    } 

    private static DataSource dataSource() { 
     JdbcDataSource dataSource = new JdbcDataSource(); 
     dataSource.setURL(JDBC_URL); 
     dataSource.setUser(USER); 
     dataSource.setPassword(PASS); 
     return dataSource; 
    } 

    @Test 
    @ExpectedDatabase("login.xml") 
    public void testShowForm() throws Exception { 
     mockMvc.perform(get("/login")).andExpect(status().isOk()).andExpect(view().name("/login")) 
       .andExpect(forwardedUrl("../../WebContent/j/login.jsp")) 
       .andExpect(model().attribute("form", hasProperty("passportId", nullValue()))) 
       .andExpect(model().attribute("form", hasProperty("email", isEmptyOrNullString()))) 
       .andExpect(model().attribute("form", hasProperty("username", isEmptyOrNullString()))) 
       .andExpect(model().attribute("form", hasProperty("hostname", isEmptyOrNullString()))) 
       .andExpect(model().attribute("form", hasProperty("pass", isEmptyOrNullString()))); 
    } 

}

Answer 1

我有固定我的PROBL em像这样...更改classpath：LoginControllerTest2-context.xml至file：LoginControllerTest2-context.xml。我以相同的方式更改xml文件中的路径。我也更改mockMvc - this.mockMvc = MockMvcBuilders.webApplicationContextSetup（this.wac）.build（）;到mockMvc = MockMvcBuilders.webApplicationContextSetup（wac）.build（）;

我使用的一些labraries不兼容，我更改了我使用的版本。
