@FormParam case sensitivity in Java Jersey

问题

I am using Java with Jersey 1.16.

Is the name of a @FormParam parameter case sensitive? Can I somehow force it to be NON case sensitive? (hopefully in some global way).

回答1:

You could filter the requests:

public class CaseFilter implements ContainerRequestFilter {

  @Override
  public ContainerRequest filter(ContainerRequest request) {
    for (Entry<String, List<String>> entry: request.getFormParameters().entrySet()) {
      request.getFormParameters().put(entry.getKey().toLowerCase(), entry.getValue());
    }
    return request;
  }

}

And update web.xml accordingly:

...
<init-param>
  <param-name>com.sun.jersey.spi.container.ContainerRequestFilters</param-name>
  <param-value>org.example.CaseFilter</param-value>
</init-param>
...
