项目结构

db.properties

jdbc.username=rootjdbc.password=rootjdbc.driverClass=com.mysql.jdbc.Driverjdbc.jdbcUrl=jdbc:mysql:///db_bookjdbc.initPoolSize=5jdbc.maxPoolSize=10

JDBCProperties

package com.konglingfu.propertiesDemo;import org.springframework.beans.factory.annotation.Value;public class JDBCProperties {    @Value("#{configProperties['jdbc.username']}")    private String userName;    @Value("#{configProperties['jdbc.jdbcUrl']}")    private String jdbcUrl;    @Value("#{configProperties['jdbc.password']}")    private String password;    @Value("#{configProperties['jdbc.driverClass']}")    private String driverClass;    @Value("#{configProperties['jdbc.initPoolSize']}")    private String initPoolSize;    @Override    public String toString() {        return "JDBCProperties [userName=" + userName + ", jdbcUrl=" + jdbcUrl                + ", password=" + password + ", driverClass=" + driverClass                + ", initPoolSize=" + initPoolSize + "]";    }}

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.AbstractJUnit4SpringContextTests;import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;import com.konglingfu.propertiesDemo.JDBCProperties;@RunWith(SpringJUnit4ClassRunner.class)@ContextConfiguration(locations = "classpath:applicationContext.xml")public class PropertiesTest extends AbstractJUnit4SpringContextTests  {    @Autowired    private JDBCProperties jdbcProperties;    @Test    public void testPrintProperties(){        String result = jdbcProperties.toString();        System.out.println(result);    }}

输出结果

JDBCProperties [userName=root, jdbcUrl=jdbc:mysql:///db_book, password=root, driverClass=com.mysql.jdbc.Driver, initPoolSize=5]
