SpringMVC注解开发

注解：

注解就是类似于添加注释，但是又不跟注释完全一样，注解可以理解为将类或者方法与特定的信息进行关联。

一.使用@Controller

@Controller继承@Component注解方法，将其以单例形成放置spring容器中，然后spring会通过配置文件中的<context:component-scan>的配置，进行如下操作

1.扫描class文件，并将包含@Component及元注解为@Component的注解@Controller、@Service、@Repository或者其他自定义的的bean注册到beanFactory中。

2.然后spring在注册处理器

3.实例化处理器，然后将其放到beanPostFactory中，然后我们就可以在类中进行使用了。

4.创建bean时，会自动调用相应的处理器进行处理。

举个具体使用@Controller的实例与@RequestMapping的例子，

UseController.java

package com.zk.Controller;
 
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
 
@Controller//<bean id="UserController" class="UserController路径">
public class UserController {
    //@RequestMapping("hello")
    //访问路径注意更改
    //请求映射value="/hello.do",
    //@RequestMapping("hello")
    //@RequestMapping("/hello.do")
    //@RequestMapping(value="/hello.do")
    @RequestMapping(value="/hello.do",method=RequestMethod.GET)
    //@RequestMapping(value="/hello.do",method={RequestMethod.GET,RequestMethod.POST})
    public String myHello(){
        return "hello";
    }
}

1.传递string类型参数

可以使用@RequestMapping向后台传递参数
