如何使RestTemplate使用UriComponents和EncodingMode.

Question

我希望我的REST客户端使用Spring Web的RestTemplate，对URL参数中的所有特殊字符（不仅是非法字符）进行％编码。的Spring Web的文档指出，编码方法可以通过配置来改变DefaultUriBuilderFactory使用RestTemplate带setEncodingMode(EncodingMode.VALUES_ONLY)：String baseUrl = "http://example.com";DefaultUriBuilderFactory factory = new DefaultUriBuilderFactory(baseUrl)factory.setEncodingMode(EncodingMode.VALUES_ONLY);RestTemplate restTemplate = new RestTemplate();restTemplate.setUriTemplateHandler(factory);这应该“将UriUtils.encode（String，Charset）应用于每个URI变量值”，这反过来将“对RFC 3986中定义的URI中任何非法或具有保留含义的所有字符进行编码”。我编写了以下测试用例，以尝试证明更改为EncodingMode.VALUES_ONLY不会产生预期的效果。（具有相关性执行它org.springframework.boot:spring-boot-starter:2.0.3.RELEASE，org.springframework:spring-web:5.0.7.RELEASE，org.springframework.boot:spring-boot-starter-test:2.0.3.RELEASE）package com.example.demo.encoding;import static org.springframework.test.web.client.match.MockRestRequestMatchers.method;import static org.springframework.test.web.client.match.MockRestRequestMatchers.requestTo;import static org.springframework.test.web.client.response.MockRestResponseCreators.withSuccess;import java.nio.charset.StandardCharsets;import org.junit.Test;import org.junit.runner.RunWith;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.boot.test.autoconfigure.web.client.RestClientTest;import org.springframework.boot.web.client.RestTemplateBuilder;import org.springframework.http.HttpMethod;import org.springframework.stereotype.Component;import org.springframework.test.context.junit4.SpringRunner;import org.springframework.test.web.client.MockRestServiceServer;import org.springframework.web.client.RestTemplate;import org.springframework.web.util.DefaultUriBuilderFactory;此测试失败java.lang.AssertionError: Request URI expected:<https://host?parameter=%2B%3A%2F> but was:<https://host?parameter=+:/>。那我在做什么错？是Spring Framework中的错误，还是MockRestServiceServer在验证期望值之前对URL进行了解码？
