Spring config 项目提供了一个解决分布式系统的配置管理方案。它包含了Client和Server两个部分。 Spring cloud config Server 管理git或svn的外部配置,集中配置到所有客户端。 Spring cloud config Client 根据Spring框架的Environment和PropertySource从Spring cloud config Server 获取配置。
逻辑架构图如下:
Spring cloud config Server统一管理存储在git或者svn的配置文件,各子系统A、B集成Spring cloudconfig Client,并从Spring cloud config Server端获取相关的配置。
Spring cloud config Server 可通过Eureka Server支持集群负载均衡。
#multiple files separated by commas ","
spring.cloud.config.name=jdbc,log
spring.cloud.config.profile=test
#if svn server then trunk, if git server then master
spring.cloud.config.label=trunk
#spring cloud server address
spring.cloud.config.uri=http://127.0.0.1:9955
第三步:新建启动测试类Application,浏览器shuru
@SpringBootApplication
@RestController
public class Application
{
public static void main(String[] args)
{
SpringApplication.run(Application.class, args);
}
@Value("${foo}")
private String foo;
@RequestMapping(value = "/hi")
public String hi()
{
return foo;
}
}
GetUrlParam:function GetUrlParam(param){
var reg = new RegExp("(^|&)"+ param +"=([^&]*)(&|$)");
var r = window.location.search.substr(1).match(reg);
if(r!=null

Json在数据传输中很好用,原因是JSON 比 XML 更小、更快,更易解析。
在Java程序中,如何使用处理JSON,现在有很多工具可以处理,比较流行常用的是google的gson和alibaba的fastjson,具体使用如下:
1、读取json然后处理
class ReadJSON
{
public static void main(String[] args)
