Question

如何在过滤器方法中将响应消息正文打印为字符串，并尝试了几种响应方法(getEntityOutputStream() / getEntity() / GetContainerResponseWriter() )

public class Test implements ContainerRequestFilter , ContainerResponseFilter) { 

    @Override 
    public ContainerResponse filter(ContainerRequest request, ContainerResponse response) { 
        response. 
    } 
}

Answer 1

我使用Jersey日志记录打印出请求/响应正文

在我的ResourceConfig

中

registerInstances(new LoggingFilter(myLogger, true));

LoggingFilter的

public class LoggingFilter implements ContainerRequestFilter,  ClientRequestFilter, ContainerResponseFilter,
    ClientResponseFilter, WriterInterceptor {
...

您可以查看他们是如何做到的：https://github.com/jersey/jersey/blob/master/core-common/src/main/java/org/glassfish/jersey/filter/LoggingFilter.java

我遇到了同样的问题，这就是我最终要做的事情。基本上我返回我的实体的JSON表示，如果我可以投射它，否则我创建一个自定义响应消息。

我相信会有更好的方法来做到这一点。

private String createLoggingResponse(ContainerResponseContext resp) {

    Object entity = resp.getEntity();

    if (BaseModel.class.isInstance(entity)) {
        BaseModel model = (BaseModel) entity;
        ByteArrayOutputStream out = new ByteArrayOutputStream();
        model.toJson(out);
        return new String(out.toByteArray());

    } else {

        MediaType mediaType = resp.getMediaType();

        return "[" + entity.toString() + "," + resp.getStatusInfo().getStatusCode() + "," + resp.getStatusInfo().getReasonPhrase() + "," + mediaType.toString() + "]";
    }

}
