这个是我写的测试类用来测试spring+mybatis整合的
package paladog_blogs;

import javax.annotation.Resource;

import org.apache.log4j.Logger;

import org.junit.Test;
import org.junit.runner.RunWith;

import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;
import com.alibaba.fastjson.JSON;
import com.paladog.blog.entity.Buser;
import com.paladog.blog.service.BuserService;

@RunWith(SpringJUnit4ClassRunner.class) // 表示继承了SpringJUnit4ClassRunner类
@ContextConfiguration(locations = { "classpath:spring-mybatis.xml"})
public class TestPblogs {
private static Logger logger = Logger.getLogger(TestPblogs.class);
// private ApplicationContext ac = null;
@Resource
private BuserService buserService = null;

// @Before
// public void before() {
// ac = new ClassPathXmlApplicationContext("applicationContext.xml");
// userService = (IUserService) ac.getBean("userService");
// }

@Test
public void test1() {
    Buser user = buserService.getUserById(1);
    // System.out.println(user.getUserName());
    // logger.info("值:"+user.getUserName());
    logger.info(JSON.toJSONString(user));
}

}


这个是项目结构
图片说明

你的spring-mybatis.xml文件并不是在classpath根目录下吧,他不是在src/main/resources目录下么

qq_34726246
qq_34726246 在的呢哥,他跟mybatis文佳夹是同同级
大约 3 年之前 回复

主要是报初始化bean出错空指针啥的

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'org.mybatis.spring.mapper.MapperScannerConfigurer#0' defined in class path resource [mybatis/context-fmp-mybatis.xml]: Initialization of bean failed; nested exception is java.lang.NoSuchFieldError: NULL

我也是这样 请问最后解决了吗
