java - Spring junit NoSuchMethodException

Question

我的 junit 测试用例出现以下错误。谁能建议我应该做什么来清除这个错误。我正在使用带有 spring 4.3.2 和 junit 4.12 的 Maven 构建工具。

我的java类:我正在使用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.beans.factory.annotation.Autowired;
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

尝试将其添加到您的 pom 中:

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

您的错误表明spring-context正在尝试调用spring-aop的ScopedProxyUtils.isScopedTarget(String beanName)。

该方法存在于 4.3.2 中(自2.5起)，这只能说明spring-aop的运行时依赖是错误的。

在添加上面的依赖之前，你可以进入控制台并输入type mvn dependency:tree -Dincludes=org.springframework:spring-aop，你会发现 错误版本来自何处。
