No bean named 'userService' is defined 问题解决 maven ssh

代码：

package sy.test;

import org.junit.Test;

import org.springframework.context.ApplicationContext;

import org.springframework.context.support.ClassPathXmlApplicationContext;

import sy.service.UserServiceI;

public class TestSpring {

@Test

public void test() {

ApplicationContext ac = new ClassPathXmlApplicationContext(new String[] { "classpath:spring.xml" });

UserServiceI userService = (UserServiceI) ac.getBean("userService");

userService.test();

}

}

修改：

UserServiceI userService = (UserServiceI) ac.getBean("UserService");

userService.test();

数据库中定义了的UserService和Java类中定义的不一致，特别是大小写的问题

webservice开发总结：

注意大小写：

1.命名空间的问题

2.在实现类中添加注解

3.数据库命名与java类的service注解的命名一致

4.tomcat的部署和运行

5.单元测试

其他原因：

报错
