Spring JUnit测试错误

Spring JUnit测试错误

我尝试运行Spring JUnit测试时收到以下错误.我只是想熟悉使用Spring Framework创建JUnits.

JUnit类:

package org.xxx.springdao.mongo_datadictionary;

import static org.junit.Assert.*;

import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.ApplicationContext;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;
import org.xxx.springdao.mongo_datadictionary.SimpleSpringApp;


@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration
public class SpringJunitTest {


    @Test
    public void testSpringTest() {
        SimpleSpringApp test = new SimpleSpringApp();
        assertNotNull("Success", test);
    }

}

从Spring 3.0.6升级到3.1.0版本时,我遇到了同样的问题.这是解决方案:

您的某些依赖项被列为3.1.0版本,但它们将其传递依赖性解析为没有错误消息中列出的方法的旧版本.

如果使用Eclipse,请打开pom.xml并查看依赖关系层次结构选项卡.您声明的某些库将列为3.1.0版,但其解析依赖关系为3.0.6.对我来说,我在我的pom中将spring-security-config和spring-security-taglib列为3.1版,但是他们将spring-core和spring-expression等依赖关系解析为3.0.6.

要解决此问题,请在pom中明确列出每个最高传递依赖项.例如,我原本指望使用spring-security-config来引入spring-core作为传递依赖,所以我没有在我的pom中列出spring-core artifact.但为了解决这个问题,我改变了我的pom以明确包含spring-core(版本3.1.0).我为我的pom中的每个已解析的依赖项添加了直接依赖项,这些依赖项已被解析为旧版本,然后它才起作用!

希望这可以帮助...
