1、添加配置
author.name=张三
author.age=20
2、类型安全的Bean
package com.example.springboot.config;
import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.stereotype.Component;
@ConfigurationProperties(prefix = "author")
@Component
public class AuthorSettings {
private String name;
private Long age;
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public Long getAge() {
return age;
}
public void setAge(Long age) {
this.age = age;
}
}
3、测试
package com.example.springboot.controller;
import com.example.springboot.config.AuthorSettings;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
@RestController
public class TestAuthor {
@Autowired
private AuthorSettings author;
@RequestMapping("/")
public String index() {
return "author name is " + author.getName() + " and age is " + author.getAge();
}
}
