SpringBoot的配置文件中,除了后面讲的根本配置形式。还能够配置List,Map,随机值等高级数据类型
配置随机数
com.rumenz.random=${random.value}com.rumenz.num=${random.int}com.rumenz.long.val=${random.long}com.rumenz.uuid=${random.uuid}com.rumenz.range=${random.int[100,1000]}测试案例
package com.rumenz.lession7.controller;import org.springframework.beans.factory.annotation.Value;import org.springframework.stereotype.Controller;import org.springframework.web.bind.annotation.RequestMapping;import org.springframework.web.bind.annotation.ResponseBody;/** * @className: RumenzController * @description: TODO 类形容 * @author: 入门小站 rumenz.com * @date: 2021/11/6 **/@Controller@RequestMapping("/rumenz")public class RumenzController { @Value("${com.rumenz.random}") private String random; @Value("${com.rumenz.num}") private Integer num; @Value("${com.rumenz.long.val}") private Long longVal; @Value("${com.rumenz.uuid}") private String uuid; @Value("${com.rumenz.range}") private Integer range; @RequestMapping("/index") @ResponseBody public String index(){ //配置文件中的随机值 String res=String.format("random %s num %d longVal %d uuid %s range %d",random,num,longVal,uuid,range); return res; }}浏览器拜访http://127.0.0.1:8080/rumenz/index返回random b92abe98c8eae52089dd78ae24fd47f5 num 354638503 longVal -7870587366296902654 uuid b3994be3-c183-4e2b-a375-55e27c28faef range 929
List类型
application.properties中配置com.rumenz.id[0]=1com.rumenz.id[1]=2com.rumenz.id[2]=3com.rumenz.uid=1,2,3,4测试案例
package com.rumenz.lession7.controller;import org.springframework.beans.factory.annotation.Value;import org.springframework.boot.context.properties.ConfigurationProperties;import org.springframework.stereotype.Controller;import org.springframework.web.bind.annotation.RequestMapping;import org.springframework.web.bind.annotation.ResponseBody;import java.util.List;import java.util.Map;/** * @className: RumenzController * @description: TODO 类形容 * @author: 入门小站 rumenz.com * @date: 2021/11/6 **/@Controller@RequestMapping("/rumenz")@ConfigurationProperties(prefix = "com.rumenz")public class RumenzController { //下标配置的数组值注入 private List<Integer> id; public List<Integer> getId() { return id; } public void setId(List<Integer> id) { this.id = id; } //逗号分隔 @Value("#{'${com.rumenz.uid}'.split(',')}") private List<Integer> uidList; @RequestMapping("/index1") @ResponseBody public String index1(){ //配置文件中的随机值 return getId().toString(); } @RequestMapping("/index2") @ResponseBody public String index2(){ //配置文件中的随机值 return uidList.toString(); }}拜访
http://127.0.0.1:8080/rumenz/index1返回[1, 2, 3]拜访
http://127.0.0.1:8080/rumenz/index2返回[1, 2, 3, 4]
Map类型
application.properties中配置com.rumenz.map={name:'rumenz.com',age:10}测试案例
package com.rumenz.lession7.controller;import org.springframework.beans.factory.annotation.Value;import org.springframework.boot.context.properties.ConfigurationProperties;import org.springframework.stereotype.Controller;import org.springframework.web.bind.annotation.RequestMapping;import org.springframework.web.bind.annotation.ResponseBody;import java.util.List;import java.util.Map;/** * @className: RumenzController * @description: TODO 类形容 * @author: 入门小站 rumenz.com * @date: 2021/11/6 **/@Controller@RequestMapping("/rumenz")@ConfigurationProperties(prefix = "com.rumenz")public class RumenzController { @Value("#{${com.rumenz.map}}") private Map<String,String> map; @RequestMapping("/index3") @ResponseBody public String index3(){ //配置文件中的随机值 return map.toString(); }}拜访
http://127.0.0.1:8080/rumenz/index3返回{name=rumenz.com, age=10}本小结源码地址:
