Jersey端点在queryparam中使用“ +”

Question

I want to design an endpoint similar to

$host/api/products?price=under+5

How can I use '+' in queryparam?

I could do like this to get that url

@GET
@Path("/products?price=under+{price}")

But How can I do using @QueryParam? If I use the following,

@GET
@Path("/products")
@UnitOfWork
public Response getProducts(@NotNull @QueryParam("price") String price) {

I get

$host/api/products?price=5

Answer 1

The value of the price query parameter must be URL encoded . When URL encoded, the + character becomes %2B . So you'll have under%2B5 .

With it, the following should work fine:

@GET
@Path("/products")
public Response getProducts(@NotNull @QueryParam("price") String price) {
    // the value of price will be: under+5
    ...
}

If you don't want the JAX-RS runtime to decode the price parameter, annotate it with @Encoded .
