问题：
@ApiOperation(value = "", notes = "查看关键词列表")
@ResponseBody
@RequestMapping(value = "getByKeywords", method = RequestMethod.GET, produces = "application/json;charset=utf-8")
Result<Page<List<AplQuestionAnswer>>> listQuestionAndAnswers(
@ApiParam(required = true, name = "keywords", value = "关键词") @RequestParam(value = "keywords", required = true) String[] keywords,
@ApiParam(required = false, name = "pageSize", value = "页大小", defaultValue = "20") @RequestParam(value = "pageSize", required = false, defaultValue = "20") int pageSize,
@ApiParam(required = false, name = "pageIndex", value = "当前页", defaultValue = "0") @RequestParam(value = "pageIndex", required = false, defaultValue = "0") int pageIndex
) { //如果为空则查询全部
if (keywords == null || keywords.length == 0) {
keywords = new String[]{};
}
前端通过swagger的方式进行获取：（注意数组在swagger中直接用回车进行获取）
问题定位：
平台码为iso-8859-1造成的，在拿到是开之后先进行解码并转码。
最终解决方式：
public static String decodeAndTrim(String str) throws UnsupportedEncodingException {
if (str == null) {
return null;
}
String encoding = TemplateStringUtil.getEncoding(str);
if ("ISO-8859-1".equals(encoding)) {
str = new String(str.getBytes("ISO-8859-1"), "utf-8");
}
return str.trim();
}
尝试过的方案：（同事通过这种方式解决了，但是我这里没有）
在tomcat 的JVM option中增加
-Dfile.encoding=UTF-8
和tomcat中的配置
<Connector executor="tomcatThreadPool"
port="8080" protocol="HTTP/1.1"
connectionTimeout="20000"
redirectPort="8443" /> 中增加 URIEncoding="UTF-8" <Connector executor="tomcatThreadPool"
port="8080" protocol="HTTP/1.1"
connectionTimeout="20000"
redirectPort="8443" URIEncoding="UTF-8"/>
