2.application.yml
server:
port: 8888
servlet:
context-path: /demo2
#自定义配置
test1: 哈哈
#自定义带前缀
my:
name: DencyCheng
age: 25
height: 176cm
3.定于属性文件类 MyProperties
package com.dencycheng.demo2.properties;
import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.stereotype.Component;
/**
* My属性配置文件
* @author DencyCheng
*/
@Component
@ConfigurationProperties(prefix = "my")
public class MyProperties {
private String name;
private Integer age;
private String height;
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public Integer getAge() {
return age;
}
public void setAge(Integer age) {
this.age = age;
}
public String getHeight() {
return height;
}
public void setHeight(String height) {
this.height = height;
}
}
4.调用
package com.dencycheng.demo2.controller;
import com.dencycheng.demo2.properties.MyProperties;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
/**
* @author DencyCheng
*/
@RestController
public class Demo2Controller {
@Value("${test1}")
private String test1;
@Autowired
private MyProperties myProperties;
@RequestMapping("/test1")
public String test1() {
return test1;
}
@RequestMapping("/test2")
public String test2() {
return "name=" + myProperties.getName()
+ ",age=" + myProperties.getAge()
+ ",height=" + myProperties.getHeight();
}
}
