Java 使用JAX-RS resteasy和ContainerRequestFilter/ContainerResponseFilter记录请求

我想记录整个请求和响应主体。为了记录日志，jax-rs具有过滤器

public class ResponseLoggingFilter implements ContainerRequestFilter, ContainerResponseFilter {
    public void filter(ContainerRequestContext requestContext, ContainerResponseContext responseContext) throws IOException { 
        System.out.println(IOUtils.toString(requestContext.getEntityStream(), "UTF-8")); // It's always empty string
        System.out.println(responseContext.getEntity().toString());  // Here is actual response. It's OK
    }
    public void filter(ContainerRequestContext requestContext) throws IOException { 
        System.out.println(IOUtils.toString(requestContext.getEntityStream(), "UTF-8")); // Here is actual response. But this request is empty in main code. 
    }
}

在响应筛选器中，我无法获取请求正文。 在请求筛选器中，我无法获得它，但：

• 我无法获得请求正文和响应正文之间的链接
• 一旦从流中写入请求体，将此流设置为空，我无法在主代码中获取它

我正在使用resteasy 3.0.6。

1。要在请求和响应之间建立连接，请使用：

@Override
    public void filter(ContainerRequestContext paramContainerRequestContext, ContainerResponseContext paramContainerResponseContext) throws IOException {
        ...     
    }

要将流返回到主代码，请使用

setEntityStream

将其写回：

ByteArrayOutputStream out = new ByteArrayOutputStream();
InputStream in = requestContext.getEntityStream();

final StringBuilder b = new StringBuilder();
try {
    ReaderWriter.writeTo(in, out);

    byte[] requestEntity = out.toByteArray();
    ...
    requestContext.setEntityStream(new ByteArrayInputStream(requestEntity));

使用@Moritz Becker注释添加请求正文和响应正文之间的链接示例，来自：

1.在ContainerResponseFilter requestContext.getEntityStream（）中，它始终为空。2.很有效，谢谢！1.您可以执行其他操作，如requestContext.getHeaderString（“访问控制请求标头”）或requestContext.getProperty（“随机令牌”）也可以，但响应正文为空，我看不到将请求正文从ContainerRequestFilter链接到ContainerResponseFilter中的响应正文的解决方案，有关如何记录请求/响应的信息，请参见

org.glassfish.jersey.logging.ClientLoggingFilter

。

@Override
    public void filter(final ClientRequestContext requestContext, final ClientResponseContext responseContext)
            throws IOException {
        ...
        final Object requestId = requestContext.getProperty(LOGGING_ID_PROPERTY);
        final long id = requestId != null ? (Long) requestId : _id.incrementAndGet();

        final StringBuilder b = new StringBuilder();

        printResponseLine(b, "Client response received", id, responseContext.getStatus());
        printPrefixedHeaders(b, id, RESPONSE_PREFIX, responseContext.getHeaders());
