springboot 配置文件

1、工程结构

2、启动类ApplicationDemo

package com.cmsz;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.context.properties.EnableConfigurationProperties;
import com.cmsz.config.PrivilegeSettings;

//加载默认的配置
@SpringBootApplication
//加载自己的配置类
@EnableConfigurationProperties({PrivilegeSettings.class})
public class ApplicationDemo{

public static void main(String[] args){
	SpringApplication.run(ApplicationDemo.class, args);
}

}

3、配置类
package com.cmsz.config;
import org.springframework.boot.context.properties.ConfigurationProperties;
//配置类上写明自己的配置文件路径classpath:/config/myapplication.properties
@ConfigurationProperties(prefix="privilege", locations = "classpath:/config/myapplication.properties")
public class PrivilegeSettings {
private String superman;
private String assistor;
private String admin;

//getter and setter
}

4、测试类

package com.cmsz.control;
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;
import com.cmsz.config.PrivilegeSettings;

@RestController
public class TestController {

@Autowired
private  PrivilegeSettings privilegeSettings ;

@Value("${name}")
private String firstName;
	@RequestMapping(value="/test")
	public String test(){
		System.out.println(privilegeSettings.getAdmin());
		System.out.println(privilegeSettings.getAssistor());
		System.out.println(firstName);
		
		return "ok";
	}

}

5、重点:配置文件的位置
默认加载resource路径下的appilication.properties
如果还有其他的配置文件,可以在resource目录下新建config文件夹,编写自己的配置文件myapplication.properties

6、配置文件的注解配置:
//加载默认的配置
@SpringBootApplication
//加载自己的配置类
@EnableConfigurationProperties({PrivilegeSettings.class})

//配置类上写明自己的配置文件路径classpath:/config/myapplication.properties
@ConfigurationProperties(prefix="privilege", locations = "classpath:/config/myapplication.properties")
