我正在做spring + hibernate应用程序.当我在tomcat服务器上运行应用程序时,我遇到了一些例外.

我有2个独立的数据库,我试图在存储库中访问它们.不幸的是,我收到以下异常.

我尝试过的事情

• 尝试将其中一个bean作为Primary.
• 使用了PersistenceContext,如下面的代码所示.

我的ExceptionTrace

I'm having the following error:

使用Spring进行单元测试的最佳实践方法是什么？我假设SpringN的组合TestNG和jmockit并不坏,所以这就是我现在正在做的事情,但如果我当然没有为我的新Spring项目选择工具,请马上告诉我.:-)

无论如何,我已经创建了一个我想测试的实体,但我不确定如何从Spring上下文中实际运行TestNG.我创建了一个简单的测试类

package com.mydomain.data.entities.test;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.ApplicationContext;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.testng.AbstractTestNGSpringContextTests;
import org.testng.Assert;
import org.testng.annotations.*;

@ContextConfiguration(locations={"classpath:applicationContext.xml"}) 
public class SimpleTest extends AbstractTestNGSpringContextTests {

    @Autowired
    private ApplicationContext applicationContext;

    @BeforeClass
    protected void setUp() throws Exception {
        Assert.assertNotNull(applicationContext);
    }

    @Test
    public void testNothing() {

    }

}

使用applicationContext.xml导入bean以设置模型和业务层.首先,我希望它使用Project/WebRoot/WEB-INF中的applicationContext.xml,而此测试的源代码位于Project/src/com/mydomain/data/entities/test中,但我相信/applicationContext.xml会给我Projects/src,和classpath一样:这是正确的吗？

此外,既然我正在使用我的Web应用程序将使用的模型和业务层,我应该期望它的行为类似.但是,当我在测试中启动TestNG时,它是sais:class org.hibernate.cfg.ExtendedMappings将接口org.hibernate.cfg.Mappings作为超类:

Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'sessionFactory' defined in URL [file:/Users/niklas/Documents/Eclipse/Project/WebRoot/WEB-INF/Project-Model.xml]: Invocation of init method failed; nested exception is java.lang.IncompatibleClassChangeError: class org.hibernate.cfg.ExtendedMappings has interface org.hibernate.cfg.Mappings as super class

我有一个带有 JPA 的 SpringBoot + Maven 项目。当尝试运行应用程序时，我收到以下错误堆栈。
