188.8.131.52. About Interceptor Precedence Families
Interceptors can be sensitive to the order they are invoked. RESTEasy groups interceptors in families to make ordering them simpler. This reference topic covers the built-in interceptor precedence families and the interceptors associated with each.
- SECURITY interceptors are usually PreProcessInterceptors. They are invoked first because as little as possible should be done before the invocation is authorized.
- HEADER_DECORATOR interceptors add headers to a response or an outgoing request. They follow the security interceptors as the added headers may affect the behavior of other interceptor families.
- ENCODER interceptors change the OutputStream. For example, the GZIP interceptor creates a GZIPOutputStream to wrap the real OutputStream for compression.
- REDIRECT interceptors are usually used in PreProcessInterceptors, as they may reroute the request and totally bypass the JAX-RS method.
- DECODER interceptors wrap the InputStream. For example, the GZIP interceptor decoder wraps the InputStream in a GzipInputStream instance.
