SpringBoot 优化内嵌的Tomcat

在通过SpringBoot调用其它服务时，报错

org.springframework.web.client.ResourceAccessException: I/O error on POST request for "http://18.16.200.110:8083/app/user/login": Read timed out; nested exception is java.net.SocketTimeoutException: Read timed out
    at org.springframework.web.client.RestTemplate.doExecute(RestTemplate.java:633)
    at org.springframework.web.client.RestTemplate.execute(RestTemplate.java:580)
    at org.springframework.web.client.RestTemplate.postForEntity(RestTemplate.java:407)

有两种解决方案

1.直接在application.properties中添加：

server.connection-timeout=3000

2.直接在SpringBoot启动类中添加，参考下面的链接
