获取接口方式（Bean注入方式总结）

一、在工具类中使用SpringContextHolder获取Bean对象，用来调用各个接口

 /**
     * 获取阿里巴巴属性列表映射
     *
     * @author 王子威
     * @param alibabaProductId
     * @return
     */
    public static void getTest(Long alibabaProductId)
    {// 获取阿里巴巴产品列表
        AlibabaProductService alibabaProductService = SpringContextHolder.getBean("rpcAlibabaProductService", AlibabaProductService.class);
        AlibabaProductCustom query = new AlibabaProductCustom();
        query.setProductId(alibabaProductId);
        List<AlibabaProduct> alibabaProducts = alibabaProductService.getAlibabaProductList(query)；
   }

 

 

二、使用@Resource注解注入Bean对象

　　

public class WzwTest
{
    @Resourceprivate JdbcTemplate jdbcTemplate;

    @Test
    public void test1() throws IOException
    {
         String sql = "SELECT * from user where id = 1";
         List<Map<String, Object>> queryForList = jdbcTemplate.queryForList(sql);
    }
}
  

 

三、使用@Autowired注解注入Bean对象

public class WzwTest
{
    @Autowired
    private JdbcTemplate jdbcTemplate;

    @Test
    public void test1() throws IOException
    {
         String sql = "SELECT * from user where id = 1";
         List<Map<String, Object>> queryForList = jdbcTemplate.queryForList(sql);
    }
}

 

@Resource和@Autowired的区别
