SpringMvc向request域中设置数据

现在我们尝试不使用Spring的XML文件来配置了，全权交给Java来做

1 编写pojo类

这个类要被Spring接管，要被注册到容器中

package com.wq.pojo;

import org.springframework.beans.factory.annotation.Value;
import org.springframework.stereotype.Component;

@Component
public class User {
    @Value("光头强")
    private String name;
    @Value("20")
    private int age;

    @Override
    public String toString() {
        return "User{" +
                "name='" + name + '\'' +
                ", age=" + age +
                '}';
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public int getAge() {
        return age;
    }

    public void setAge(int age) {
        this.age = age;
    }
}

2 编写config类

package com.wq.config;

import com.wq.pojo.User;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

@Configuration
public class WqConfig {
    @Bean
    public User getUser(){
        return new User();
    }
}
