Question

package com.maroclance.university.service;

import static org.junit.Assert.*;

import org.junit.AfterClass;
import org.junit.BeforeClass;
import org.junit.Test;
import org.springframework.context.support.ClassPathXmlApplicationContext;

public class ModuleServiceTest {
public class ModuleServiceTest {

private static ClassPathXmlApplicationContext context;


private static ModuleService moduleService;

@BeforeClass
public static void setUpBeforeClass() throws Exception {

    context = new ClassPathXmlApplicationContext("application-context.xml");
    moduleService=(ModuleService) context.getBean("moduleService");

}

@AfterClass
public static void tearDownAfterClass() throws Exception {
    context.close();
}

@Test
public void test() {
    fail("Not yet implemented");
}

}

我发出不使用moduleService的警告当我执行我的代码时，我有这个错误

rg.springframework.beans.factory.BeanCreationException: Error creating bean with name 'sessionFactory' defined in class path resource [application-context.xml]: Invocation of init method failed; nested exception is org.hibernate.AnnotationException: Use of @OneToMany or @ManyToMany targeting an unmapped class: com.maroclance.model.Matiere.profMats[com.maroclance.model.ProfMat]

我真的被阻止了

Answer 2

其中一个类ProfMat或Module未映射到Hibernate。应通过配置定义映射。如果您正在使用注释配置，则在关联的类上放置@Table注释，并确保扫描类以进行注释。

字段moduleService的值未使用
