我有一个像这样的简单 HTTP GET 请求:
http://localhost:8080/search?page=0&size=20&sort=id,asc&description=1+3
还有一个 RestController:
@RequestMapping(value = "/search", method = RequestMethod.GET, produces = MediaType.APPLICATION_JSON_VALUE)
public ResponseEntity<List<TestEntity>> search(Pageable pageable, @RequestParam("description") String description) {
Page<TestEntity> page = service.search(pageable, description);
HttpHeaders headers = PaginationUtil.generatePaginationHttpHeaders(page);
return ResponseEntity
.ok()
.headers(headers)
.body(page.getContent());
}
但是 @RequestParam
"description"的值是 "1 3"。
我做错了什么?
或者我应该怎么做才能在 Spring @RequestParam
中将“+”之类的信号反序列化为“+”?
这是我的 pom.xml

最佳答案
一切如期而至。根据 RFC3986在 URL 编码中 +
是一个保留字符。根据第 2.2 点。保留字符:
If a reserved character is found in a URI component and no delimiting role is known for that character, then it must be interpreted as representing the data octet corresponding to that character's encoding in US-ASCII.
要使用 +
作为值,您需要将其编码为 %2B
,如 Percent-encoding reserved characters 中所述。 .这将使您的网址:
http://localhost:8080/search?page=0&size=20&sort=id,asc&description=1%2B3
请注意,有时 Spring 在处理 +
时会不一致,例如SPR-16860 Spring is inconsistent in the encoding/decoding of URLs错误。
