将POST的有效负载记录到Tomcat

由于没有建议使用内置方法来获取POST负载，因此我继续编写了一个自定义过滤器来转储负载的内容。特别：

public void doFilter(ServletRequest servletRequest, ServletResponse servletResponse,          FilterChain chain) throws IOException, ServletException {    HttpServletRequest request = (HttpServletRequest) servletRequest;    LOG.debug("payload: " + requestWrapper.getRequestBody());

和web.xml：

<filter>    <filter-name>PayloadLoggingFilter</filter-name>    <filter-class>com.host.PayloadLoggingFilter</filter-class></filter><filter-mapping>    <filter-name>PayloadLoggingFilter</filter-name>    <url-pattern>/resources/*</url-pattern></filter-mapping>
