环境依赖

sprint-boot version 2.1.7

java version 1.8

pom.xml 依赖jar包

org.springframework.boot

spring-boot-configuration-processor

true

test.properties

username=test

password=123456

info.age=26

看下目录布局

testconfig.java 加载配置的类文件

//prefix 为空则加载整个配置文件中的 参数

@configurationproperties(prefix = "")

@propertysource("classpath:test.properties")

//注意一定要注册

@component

public class testconfig {

private string username;

private string password;

private info info;

public void setinfo(info info) {

this.info = info;

}

public info getinfo() {

return info;

}

public string getusername() {

return username;

}

public string getpassword() {

return password;

}

public void setusername(string username) {

this.username = username;

}

public void setpassword(string password) {

this.password = password;

}

public static class info{

private integer age;

public integer getage() {

return age;

}

public void setage(integer age) {

this.age = age;

}

@override

public string tostring() {

return "info{"

"age=" age

'}';

}

}

@override

public string tostring() {

return "testconfig{"

"username='" username '\''

", password='" password '\''

", info=" info

'}';

}

}

hellocontroller.java 用来测试

@controller

public class hellocontroller {

@autowired

testconfig testconfig;

@responsebody

@getmapping("/hello")

public string sayhello()

{

//读取配置

return "age=" testconfig.getinfo().getage();

}

@responsebody

@getmapping("username")

public string getusername()

{

//读取配置测试

return testconfig.getusername();

}

}
