问题内容

httpclient调用本地其他服务，或者第三方系统接口，出现如下图问题：

准备内容

httpclient的maven依赖

    <dependency>
      <groupId>org.apache.httpcomponents</groupId>
      <artifactId>httpclient</artifactId>
      <version>4.5.10</version>
    </dependency>

新建项目

1.新建一个SpringBoot项目

package com.example.temp;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.annotation.Description;
import org.springframework.web.bind.annotation.*;

import java.util.Map;

@RestController
@SpringBootApplication
public class TempApplication {

    @Description("模拟本地其他服务接口，或者第三方接口")
    @PostMapping(path = "/postContent")
    public void postContent(@RequestBody Map<String,Object> mapContent) {
        System.out.println(mapContent);
    }

    public static void main(String[] args) {
        SpringApplication.run(TempApplication.class, args);
    }

}

2.新建一个客户端调用接口

package org.example;

import org.apache.http.client.methods.CloseableHttpResponse;
import org.apache.http.client.methods.HttpPost;
import org.apache.http.entity.StringEntity;
import org.apache.http.impl.client.CloseableHttpClient;
import org.apache.http.impl.client.HttpClients;
import org.apache.http.util.EntityUtils;

import java.io.IOException;

public class HttpClientDemo {
    public static void main(String[] args) {

        try {
            String result = sendPOST();
            System.out.println(result);
        } catch (IOException e) {
            e.printStackTrace();
        }

    }

    private static String sendPOST() throws IOException {

        String result = "";
        HttpPost post = new HttpPost("http://localhost:8081/postContent");

        // json content
        String json = "{\n" +
                "    \"teslaKey\":\"teslaValue\",\n" +
                "    \"requestKey\":\"{\\\"customKey\\\":\\\"customValue\\\"}\"\n" +
                "}";

        System.out.println(json);

        // send a JSON data
        post.setEntity(new StringEntity(json));

        try (CloseableHttpClient httpClient = HttpClients.createDefault();
             CloseableHttpResponse response = httpClient.execute(post)) {

            result = EntityUtils.toString(response.getEntity());
        }

        return result;
    }

}

运行结果

1.客户端调用SpringBoot项目接口，打印问题

    "teslaKey":"teslaValue",
    "requestKey":"{\"customKey\":\"customValue\"}"
}

解决问题

1.查看SpringWeb包里面的MediaType类，是否提供"text/plain;charset=ISO-8859-1"，很不幸Spring不提供；可以根据根据实际情况，使用Spring提供的MediaType类型。

    public static final String TEXT_PLAIN_VALUE = "text/plain";

2.解决如图
