spring resttemplate中的转码

    /*
     * 初始化RestTemplate，RestTemplate会默认添加HttpMessageConverter
     * 添加的StringHttpMessageConverter非UTF-8 所以先要移除原有的StringHttpMessageConverter，
     * 再添加一个字符集为UTF-8的StringHttpMessageConvert

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);
