RestTemplate 中文亂碼解決方法

Spring4.2.2.RELEASE   RestTemplate 中文亂碼解決方法

RestTempalate 字符串類型默認StringHttpMessageConverter作轉碼，而StringHttpMessageConverter的默認編碼集是ISO8859-1,本工程編碼是UTF-8 故發送到服務器端會存在中文亂碼

第一種：把restTempalate 中  StringHttpMessageConverter 默認編碼設置爲UTF-8

具體：使用 restTempalate 構造函數 public RestTemplate(List<HttpMessageConverter<?>> messageConverters) 傳入 StringHttpMessageConverter 默認編碼集是UTF-8 的轉換器

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>

第二種：使用 設置Http請求頭中設置 Content-Type: application/x-www-form-urlencoded; charset=UTF-8 修改默認編碼

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);
