如何使用Jersey拦截器获取请求正文

这是一种可以实现的方法，与Jersey实现其日志记录过滤器的方式非常相似。您可以阅读该实体并将其粘贴回请求，因此您不小心在过滤器中不使用它。

import com.sun.jersey.api.container.ContainerException;import com.sun.jersey.core.util.ReaderWriter;import com.sun.jersey.spi.container.ContainerRequest;import com.sun.jersey.spi.container.ContainerRequestFilter;import java.io.ByteArrayInputStream;import java.io.ByteArrayOutputStream;import java.io.IOException;import java.io.InputStream;public class JerseyFilter implements ContainerRequestFilter {    @Override    public ContainerRequest filter(ContainerRequest request) {        ByteArrayOutputStream out = new ByteArrayOutputStream();        InputStream in = request.getEntityInputStream();        final StringBuilder b = new StringBuilder();        try { if (in.available() > 0) {     ReaderWriter.writeTo(in, out);     byte[] requestEntity = out.toByteArray();     printEntity(b, requestEntity);     request.setEntityInputStream(new ByteArrayInputStream(requestEntity)); } return request;        } catch (IOException ex) { throw new ContainerException(ex);        }    }    private void printEntity(StringBuilder b, byte[] entity) throws IOException {        if (entity.length == 0) return;        b.append(new String(entity)).append("n");        System.out.println("#### Intercepted Entity ####");        System.out.println(b.toString());    }}
