day2 springBoot学习笔记--动力节点

动手试试呗：1.创建一个Tiger类

package com.rll.vo;

public class Tiger {
    private String name;
    private Integer age;

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

2.新建一个config.properties文件

 3.要用中文的话就要设置file-->settings-->

 4.完善config.properties文件

 5.在Tiger类对象上加注解@Component("tiger")

- 在每个属性上加上@Value("${tiger.属性名}")

6.然后在SpringConfig.java里面的类名上面加上@PropertySource(value="文件名")

这里要找注解，就得扫描组件

@ComponentScan(basePackages = "com.rll.vo")

so:

package com.rll.config;

import com.rll.vo.Student;
import org.springframework.context.annotation.*;



@Configuration
@ImportResource(value = "classpath:applicationContext.xml")
@PropertySource(value = "classpath:config.properties")
@ComponentScan(basePackages = "com.rll.vo")
public class SpringConfig {

    

    //不指定对象的名称，默认的方法名是id
    @Bean
    public Student createStudent(){
        Student s1= new Student();
        s1.setAge(90);
        s1.setName("zyy");
        s1.setSex("man");
        return s1;
    }

    
    @Bean(name = "ListStudent")
    public Student makeStudent(){
        Student s1= new Student();
        s1.setAge(90);
        s1.setName("lisi");
        s1.setSex("man");
        return s1;
    }
}
