Spring4.2.2.RELEASE RestTemplate 中文乱码解决方法
RestTempalate 字符串类型默认StringHttpMessageConverter做转码，而StringHttpMessageConverter的默认编码集是ISO8859-1,本工程编码是UTF-8 故发送到服务器端会存在中文乱码
第一种：把restTempalate 中 StringHttpMessageConverter 默认编码设置为UTF-8
具体：使用 restTempalate 构造函数 public RestTemplate(List<HttpMessageConverter<?>> messageConverters) 传入 StringHttpMessageConverter 默认编码集是UTF-8 的转换器
在 配置文件中配置：
<bean id="restTemplate" class="org.springframework.web.client.RestTemplate">
<constructor-arg index="0">
<list>
<bean id="byteArrayHttpMessageConverter" class="org.springframework.http.converter.ByteArrayHttpMessageConverter"></bean>
<bean id="stringHttpMessageConverter" class="org.springframework.http.converter.StringHttpMessageConverter">
<constructor-arg value="UTF-8"></constructor-arg>
</bean>
<bean id="resourceHttpMessageConverter" class="org.springframework.http.converter.ResourceHttpMessageConverter"></bean>
<bean id="sourceHttpMessageConverter" class="org.springframework.http.converter.xml.SourceHttpMessageConverter"></bean>
<bean id="allEncompassingFormHttpMessageConverter" class="org.springframework.http.converter.support.AllEncompassingFormHttpMessageConverter"></bean>
<bean id="jaxb2RootElementHttpMessageConverter" class="org.springframework.http.converter.xml.Jaxb2RootElementHttpMessageConverter"></bean>
<bean id="mappingJackson2HttpMessageConverter" class="org.springframework.http.converter.json.MappingJackson2HttpMessageConverter"></bean>
</list>
</constructor-arg>
</bean>
第二种：使用 设置Http请求头中设置 Content-Type: application/x-www-form-urlencoded; charset=UTF-8 修改默认编码
HttpHeaders headers = new HttpHeaders();
MediaType type = MediaType.parseMediaType("application/x-www-form-urlencoded; charset=UTF-8");
headers.setContentType(type);
System.out.println(type);
HttpEntity<String> requestEntity = new HttpEntity<String>(PostStrUtils.getPostStrFromMap(paramMap), headers);
String msg = restTemplate.postForObject(url,requestEntity, String.class);
public String sendToRest(String url, Map<String, String> paramMap) {
logger.debug("====================start======================");
logger.debug("调用接口-" + restUrl + url + " 入参:" + paramMap);
