Using Resttemplate in Springboot.

I. Preface

Instructions for use of official website

Get Eureka Instance

Public String serviceurl () {Instanceinfo instance = Discoveryclient.getnextserverfromeureka ("STORES", false); return Instance.gethomepageurl ();}

Steps:

Two. Importing packages

Pom.xml

<dependency> <groupId>org.springframework.cloud</groupId> <artifactId> Spring-cloud-starter-eureka</artifactid></dependency><dependency> <groupId> Org.springframework.cloud</groupid> <artifactId>spring-cloud-starter-hystrix</artifactId>< /dependency>

Three. Modify the startup application

@EnableCircuitBreaker @enablediscoveryclientpublic class Helllomain {@Bean @loadbalancedresttemplate resttemplate () { return new Resttemplate ();} public static void Main (string[] args) {Springapplication.run (hellomain.class, args);}}

Four. Business use

private int xxxx (String body) {resttemplate resttemplate = new Resttemplate (); Httpheaders headers = new Httpheaders (); MediaType type = Mediatype.parsemediatype ("Application/json"); Headers.setcontenttype (type); httpentity<string> formentity = new Httpentity<string> (body, headers); String result = Resttemplate.postforobject (Geteurkaclient ("Hello-module"), Formentity,string.class); return 0;}

public string Geteurkaclient (string end) {Instanceinfo instance = Discoveryclient.getnextserverfromeureka ("Smartho Me-phihome ", false); return Instance.gethomepageurl () + END;}

This makes it possible to call each other between applications
