测试spring的注入

第一种

package com.shaokp.hrm.conn;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 org.springframework.test.context.ContextConfiguration;import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;@ContextConfiguration("classpath:spring/applicationContext.xml")@RunWith(SpringJUnit4ClassRunner.class)public class ConnTest {    @Autowired    private DataSource ds;    @Test    public void getConn() throws Exception{        Connection conn = ds.getConnection();        String sql = "select * from user_inf";        PreparedStatement ps = conn.prepareStatement(sql);        ResultSet rs =ps.executeQuery();        while(rs.next()){            System.out.println(rs.getString("loginname"));        }    }}

第二种

test：

package dao;import org.junit.Test;import org.junit.runner.RunWith;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.context.support.ClassPathXmlApplicationContext;import entity.User;public class demo {    @Test    public void pp(){        ClassPathXmlApplicationContext ac = new ClassPathXmlApplicationContext("xml/spring.xml");        System.out.println("-----容器创建-----");        User user = (User)ac.getBean("user");        System.out.println(user.getName());        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;    }}

spring

<?xml version="1.0" encoding="UTF-8"?><beans xmlns="http://www.springframework.org/schema/beans"    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"    xmlns:aop="http://www.springframework.org/schema/aop"    xmlns:context="http://www.springframework.org/schema/context"    xmlns:p="http://www.springframework.org/schema/p"    xmlns:tx="http://www.springframework.org/schema/tx"    xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd        http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.0.xsd        http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-4.0.xsd        http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.0.xsd">    <bean id="user" class="entity.User">        <property name="name" value="你好！" />         <property name="age" value="世界" />     </bean></beans>
