1.新建配置文件abc.properties
author.name=yaoge author.age=888888 author.address=sh1
2.定义AuthorSettings
package com.basic.demo;
import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.PropertySource;
@Configuration
@ConfigurationProperties(prefix="author")
@PropertySource("classpath:abc.properties")
public class AuthorSettings {
private String name;
private Integer age;
private String address;
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 getAddress() {
return address;
}
public void setAddress(String address) {
this.address = address;
}
}
3.controller
package com.basic.demo;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.context.annotation.Bean;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
/**
* desc:简单controller
* @date 2017-03-28 11:28:56
* @author 磨练中龙
*
*/
@RestController
@RequestMapping("/simple")
public class SimpleController {
@Autowired
private AuthorSettings authorSettings;
@RequestMapping("/")
public String index(){
return authorSettings.getName()+"--"+authorSettings.getAge()+"--"+authorSettings.getAddress();
}
}
4.启动项目
/**
* desc:项目启动入口
* @date 2017-03-28 11:29:39
* @author 磨练中龙
*
*/
@SpringBootApplication
@EnableConfigurationProperties(AuthorSettings.class)
public class App {
public static void main(String[] args) {
SpringApplication.run(App.class, args);
}
}
八卦下:
@ConfigurationProperties locations过期了，我们可以使用以下注解代替
@PropertySource("classpath:abc.properties")
如果使用application.properties配置文件，可以只使用这个注解，定义好前缀即可，例如：
@ConfigurationProperties(prefix="author")
