Spring junit NoSuchMethodException

Question

對於我的junit測試用例，得到低於錯誤的錯誤。任何人都可以請建議我應該做些什麼來清除這個錯誤。我使用的是spring 4.3.2和junit 4.12的maven構建工具。

我的java類：我使用java 1.8。

import java.io.UnsupportedEncodingException; 
import javax.naming.NamingException; 
import org.junit.After; 
import org.junit.Before; 
import org.junit.Test; 
import org.junit.runner.RunWith;

import org.springframework.ldap.core.LdapTemplate; 
import org.springframework.test.context.ContextConfiguration; 
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner; 

@RunWith(SpringJUnit4ClassRunner.class) 
@ContextConfiguration("classpath:testContext.xml") 
public class LdapSyncTest { 
    private LdapSync ldapSync = null; 

    @Autowired 
    private LdapTemplate ldapTemplate; 

    @Before 
    public void init() { 
     ldapSync = new LdapSync(); 
     ldapSync.setLdapTemplate(ldapTemplate); 
    } 

    @Test 
    public void testPasswordSync() throws UnsupportedEncodingException, NamingException { 
     ldapSync.doPwdUpdate("rajak1@bt.com", "uid", "BTCOM", "Tcs@12345"); 
    } 
} 

Answer 1

嘗試添加以下內容到POM：

<dependency> 
    <groupId>org.springframework</groupId> 
    <artifactId>spring-aop</artifactId> 
    <version>4.3.2.RELEASE</version> 
</dependency> 

你的錯誤顯示，spring-context試圖調用spring-aop的ScopedProxyUtils.isScopedTarget(String beanName)。

該方法存在於4.3.2（自2.5開始），這隻能意味着spring-aop的運行時依賴關係是錯誤的。

在添加上面的依賴項之前，您可以進入控制檯並鍵入type mvn dependency:tree -Dincludes=org.springframework:spring-aop，您會發現 錯誤版本來自哪裏。

這個問題的原因很明顯： 1.不正確的Spring jar版本。低於4.0 或 2.類路徑中的多個jar版本。一些舊版本也存在，因此相沖突。 3.你需要一個清潔版本。可能一切都是正確的，但需要新的構建。
