来自Jersey 2.x的过多警告消息

问题描述

 对URI的本地servlet请求（local请求URI）在请求正文中包含表单参数，但请求正文已被servlet或访问请求参数的servlet过滤器使用。只有使用@FormParam的资源方法才能按预期工作。通过其他方式使用请求主体的资源方法将无法按预期工作。 
  

我将其追溯到org.glassfish.jersey.servlet.WebComponent：

  if（！form.asMap（）。isEmpty（））{
 containerRequest.setProperty（InternalServerProperties.FORM_DECODED_PROPERTY，form）; （LOGGER.isLoggable（Level.WARNING））{
 LOGGER.log（Level.WARNING，LocalizationMessages.FORM_PARAM_CONSUMED（containerRequest.getRequestUri（）））; 
 
 if 
 
 
 
 
 
 
 $ b因此，如果有任何表单数据，打印此警告。我是否做了错误的事情，因为填写日志和正常操作的警告似乎不是一个好主意。 
解决方案
我在Slf4j中使用Logback，您只需添加 jul-to-slf4j 作为依赖关系，并将其配置在logback.xml中。 
 
 
 
在 pom.xml中：
：
 
 
 <依赖性> 
< groupId> ch.qos.logback< / groupId> 
< artifactId> logback-classic< / artifactId> 
< version> $ {logback.version}< / version> 
< /依赖关系> 
< dependency> 
< groupId> org.slf4j< / groupId> 
< artifactId> slf4j-api< / artifactId> 
< version> $ {slf4j.version}< / version> 
< /依赖关系> 
< dependency> 
< groupId> org.slf4j< / groupId> 
< artifactId> jul-to-slf4j< / artifactId> 
< version> $ {slf4j.version}< / version> 
< /依赖关系> 
  
要将jul消息重定向到logback，请将其添加到 logback.xml  ： 
 
 
 <？xml version =1.0encoding =UTF-8？> 
<配置> 
< contextListener class =ch.qos.logback.classic.jul.LevelChangePropagator> 
< resetJUL> true< / resetJUL> 
< / contextListener> 
 
< appender name =OUTclass =ch.qos.logback.core.ConsoleAppender> 
 ... 
 
< logger name =org.glassfish.jersey.servletlevel =ERROR/> 
 
< / configuration> 
  
将 org.glassfish.jersey.servlet 设置为ERROR的级别可让您避免在日志文件中发出警告消息。
 
I keep getting these warning messages from any POST operation with APPLICATION_FORM_URLENCODED form data:
A servlet request to the URI (local request URI) contains form parameters in the request body   but the request body has been consumed by the servlet or a servlet filter accessing the request parameters. Only resource methods using @FormParam will work as expected. Resource methods consuming the request body by other means will not work as expected.
I've traced this down to org.glassfish.jersey.servlet.WebComponent:
        if (!form.asMap().isEmpty()) {
            containerRequest.setProperty(InternalServerProperties.FORM_DECODED_PROPERTY, form);

            if (LOGGER.isLoggable(Level.WARNING)) {
                LOGGER.log(Level.WARNING, LocalizationMessages.FORM_PARAM_CONSUMED(containerRequest.getRequestUri()));
            }
        }
So, if there's any form data, it will always print this warning.  Am I doing something wrong as filling up the log with warnings for normal operations doesn't seem like a good idea. 
 解决方案 
I'm using Logback with Slf4j, and you only should add "jul-to-slf4j" as dependency and configure it in logback.xml.  
In pom.xml:  
<dependency>
      <groupId>ch.qos.logback</groupId>
      <artifactId>logback-classic</artifactId>
      <version>${logback.version}</version>
 </dependency>
 <dependency>
      <groupId>org.slf4j</groupId>
      <artifactId>slf4j-api</artifactId>
      <version>${slf4j.version}</version>
 </dependency>
 <dependency>
      <groupId>org.slf4j</groupId>
      <artifactId>jul-to-slf4j</artifactId>
      <version>${slf4j.version}</version>
 </dependency>
To redirect jul messages to logback, add this inside  in logback.xml:  
<?xml version="1.0" encoding="UTF-8"?>
<configuration>
    <contextListener class="ch.qos.logback.classic.jul.LevelChangePropagator">
        <resetJUL>true</resetJUL>
    </contextListener>

    <appender name="OUT" class="ch.qos.logback.core.ConsoleAppender">
    ...

    <logger name="org.glassfish.jersey.servlet" level="ERROR" />

</configuration>
Setting level for org.glassfish.jersey.servlet to ERROR lets you avoid warning messages in log files.
