葡京赌场网址Spring框架 注解annotation和布局文件混合使用(生成对象与性注入) xml配置文件并未提示解决

解决的主意是改pydelicious.py文件,也不怕是提供的API。

下一场做一个service的类Service.class

征:HTTP Error 500: Internal Server
Error错误的因由是服务器无法响应,在自身分析看来是访问的地点错误导致的。具体的辨析好参照上文提供的个别独

分别做简单个dao的类StudentDao.class 和CourseDao.class

xml配置文件并未提醒解决

使用配置文件xml生成对象

stack overflow网址。欢迎交流。

CourseDao.class类的代码如下:

解决方式:
累计有三独地方用进行修改:
(1)DLCS_RSS =
‘http://del.icio.us/rss/'改为DLCS\_RSS =
‘http://feeds.delicious.com/v2/rss/’
(2)def get_popular(tag = “”):
return getrss(tag = tag, popular =
1)
改为
def get_popular(tag = “”):
return getrss(tag = tag, popular =
0)
(3)def get_url(self, url):
return ‘http://del.icio.us/url/?url=%s’ %
(url, )
改为:

package com.swift;

import java.io.IOException;

import javax.servlet.ServletException;
import javax.servlet.annotation.WebServlet;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
@WebServlet("/test")
public class ServletTest extends HttpServlet {
    private static final long serialVersionUID = 1L;
    public ServletTest() {
        super();
    }
    protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
        response.getWriter().append("Served at: ").append(request.getContextPath());
        ApplicationContext context=new ClassPathXmlApplicationContext("beanZhujie.xml");
        Service service=(Service) context.getBean("service");
        response.getWriter().append(service.fun());
    }
    protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
        doGet(request, response);
    }

}

Service.class类的代码如下:

–>在location中点击按钮 file system–>找到spring framework
包–>schema–>beans–>最后之杀版本高的–>key
type下拉菜单选schema location

StudentDao.class类的代码如下:

<?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:context="http://www.springframework.org/schema/context" 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.xsd"> 
      <!--  开启注解扫描  -->
     <context:component-scan base-package="com.swift"></context:component-scan>
     <bean id="studentDao" class="com.swift.StudentDao"></bean>
     <bean id="courseDao" class="com.swift.CourseDao"></bean>
     <bean id="service" class="com.swift.Service"></bean>

</beans>
package com.swift;

public class CourseDao {
    public String fun() {
        return "This is CourseDao's fun().......";
    }
}

使用注注入属性

每当近似的性能上直接通过annotation注解的措施注入对象属性
,这个目标是当xml配置文件中生成的,配置文件代码如下:

 

 

末了通过一个Servlet类ServletTest.class进行测试

浏览器结果使下图:

package com.swift;

import javax.annotation.Resource;

public class Service {
    @Resource(name="studentDao")
    private StudentDao studentDao;
    @Resource(name="courseDao")
    private CourseDao courseDao;
    public String fun() {
        return "This is Service's fun()........."+this.studentDao.fun()+this.courseDao.fun();
    }
}

window –>preferences–>搜索 xml catalog
–>add–>在key中输入约束网址http://www.springframework.org/schema/beans/spring-beans.xsd

ServletTest.class类的代码如下:
