测试spring是否注入成功两种方法

测试spring的注入

第一种

package com.;import java.sql.Connection;
import java.sql.PreparedStatement;
import java.sql.ResultSet;import javax.sql.DataSource;import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import st.context.ContextConfiguration;
import st.context.junit4.SpringJUnit4ClassRunner;@ContextConfiguration("classpath:l")
@RunWith(SpringJUnit4ClassRunner.class)
public class ConnTest {@Autowiredprivate DataSource ds;@Testpublic void getConn() throws Exception{Connection conn = ds.getConnection();String sql = "select * from user_inf";PreparedStatement ps = conn.prepareStatement(sql);ResultSet rs &#uteQuery();()){System.out.String("loginname"));}}}

第二种

test：

package dao;import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import t.support.ClassPathXmlApplicationContext;import entity.User;public class demo {@Testpublic void pp(){ClassPathXmlApplicationContext ac = new ClassPathXmlApplicationContext("l");System.out.println("-----容器创建-----");User user = (Bean("user");System.out.Name());System.out.println(user);}
}

bean

package entity;public class User {private String name;private String age;public String getName() {return name;}public void setName(String name) {this.name = name;}public String getAge() {return age;}public void setAge(String age) {this.age = age;}}
