java - 来自 Jersey 2.x 的过多警告消息

Question

我不断从任何使用 APPLICATION_FORM_URLENCODED 表单数据的 POST 操作中收到这些警告消息:

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.

我已经将其追溯到 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()));
            }
        }

因此，如果有任何表单数据，它将始终打印此警告。我是不是做错了什么，因为用正常操作的警告填充日志似乎不是一个好主意。

我将 Logback 与 Slf4j 一起使用，您只需添加“jul-to-slf4j”作为依赖项并在 logback.xml 中配置它。

在 pom.xml 中:

<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>

要将 jul 消息重定向到 logback，请在 logback.xml 中添加:

<?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>

将 org.glassfish.jersey.servlet 的级别设置为 ERROR 可以避免日志文件中出现警告消息。
