1、编辑配置文件application.properties及自定义配置文件define.properties
application.properties
#访问的根路径
server.context-path=/springboot
#端口号
server.port=8081
#session失效时间
server.session-timeout=30
#编码
server.tomcat.uri-encoding=utf-8
test.name=kelly
test.password=admin123
define.properties
defineTest.pname=test
defineTest.password=test123
2、读取application.properties配置文件中的属性值
FirstController.java
package com.kelly.controller;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;
@Controller
public class FirstController {
@Value("${test.name}")
private String name;
@Value("${test.password}")
private String password;
@RequestMapping("/")
@ResponseBody
String home()
{
return "Hello Springboot!";
}
@RequestMapping("/hello")
@ResponseBody
String hello()
{
return "name: " + name + ", " + "password: " + password;
}
}
3、使用java bean的方式读取自定义配置文件 define.properties
DefineEntity.java
package com.kelly.entity;
import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.context.annotation.PropertySource;
import org.springframework.stereotype.Component;
@Component
@ConfigurationProperties(prefix="defineTest")
@PropertySource("classpath:define.properties")
public class DefineEntity {
private String pname;
private String password;
public String getPname() {
return pname;
}
public void setPname(String pname) {
this.pname = pname;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
}
注:读取配置文件的方式两种都可以
@PropertySource("classpath:define.properties")
@PropertySource(value="define.properties")
