只需要社区评估的东西.以下是一段代码,它是一个创建特定类型实例的简单工厂.该方法将在上下文中将bean注册为原型并返回实例.这是我第一次在运行时配置bean.你能评价并提供反馈意见吗？先感谢您.

package au.com.flexcontacts.flexoperations;

import org.springframework.beans.BeansException;

import org.springframework.context.ApplicationContext;
import org.springframework.context.ApplicationContextAware;
import org.springframework.context.support.AbstractApplicationContext;

想问一个关于spring-mvc控制器的最佳实践问题.请查看以下代码:

    @Autowired
    SomeService service;

    @RequestMapping (...)
    public @ResponseBody Response createSomething () {

       try {

            serviceResponse = service.doSomething();

            //create a success response and return

       }
       catch (SomeServiceException e) {
             //create an error response and return 
       }

}

错误处理是否在控制器级别正常进行？或者服务类是否应该抛出如上所示的异常.请查看并告知我们.

我正在使用Spring In Action(第3版)一书学习Spring.我在书中遇到了一个不适合我的例子.以下是详细信息:

我试图使用Spring AOP在bean中引入新功能:

这是类结构:

1. 乐器演奏者实现了演奏者
2. GraciousContestant实现了参赛者

执行者界面

public interface Performer {
    void perform();
}

班级乐器演奏家

package chapter4;

public class Instrmentalist implements Performer {
    public void perform() {
        System.out.println("Sining hey hey, hey");
    }
}

参赛者界面

package chapter4;

public interface Contestant {
    void receiveAward();
}

GraciousContestant Class

package chapter4;

public class GraciousContestant implements Contestant {
    public void receiveAward() {
        System.out.println("Won a car worth 4K!");
    }
}

我的Spring配置文件名为"spring-idol2.xml"如下:
