SpringMVC-成功通过param传递参数

继续学习SpringMVC，JSON和Param是两种常用的传值的方法，其中JSON是用的最为普遍的，而现在我们来学习一下另一种方法就是param

最终结果：

 由图可见我们成功访问到了所输的数值，换一个数字照样行得通

 简要实现：

package com.aurora.param;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;

@Controller
@RequestMapping("param")
public class ParamController {

    //  直接接收
    //  /param/data?name=root&age=18
    //  形参列表，填写对应名称的参数即可，请求参数名 = 形参参数名即可
    //
    @RequestMapping("data")
    @ResponseBody
    public String data(String name,int age){

        System.out.println("name = " + name + ", age = " + age);
        return "name = " + name + ", age = " + age;
    }
    
}

package com.aurora.config;

import org.springframework.web.servlet.support.AbstractAnnotationConfigDispatcherServletInitializer;

public class SpringMVCInit extends AbstractAnnotationConfigDispatcherServletInitializer {
    @Override
    protected Class<?>[] getRootConfigClasses() {
        return new Class[0];
    }

    @Override
    protected Class<?>[] getServletConfigClasses() {
        return new Class[]{MvcConfig.class};
    }

    @Override
    protected String[] getServletMappings() {
        return new String[]{ "/" };
    }
}

package com.aurora.config;

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerAdapter;
import org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerMapping;

@Configuration
@ComponentScan("com.aurora.param")
public class MvcConfig {

    @Bean
    public RequestMappingHandlerMapping handlerMapping(){
        return new RequestMappingHandlerMapping();
    }
    @Bean
    public RequestMappingHandlerAdapter handlerAdapter(){
        return new RequestMappingHandlerAdapter();
    }
}
