Spring Boot 3中如何关闭控制台的SAXException日志输出

环境与依赖 #

使用Spring Boot v3.1.1 + JAVA 17开发后端服务，通过以下JAX-RPC依赖与内部服务通信：

implementation 'wsdl4j:wsdl4j:1.6.3'
implementation 'org.apache.axis:axis:1.4'
implementation 'org.apache.axis:axis-jaxrpc:1.4'
implementation 'org.codehaus.woodstox:stax2-api:4.2'

问题现象 #

开发阶段无异常，流程正常，但生产环境中org.xml.sax.SAXException导致日志体积持续增大，异常日志片段如下：

06-Jul-2023 04:00PM ERROR 1 --- [nio-8080-exec-2] o.a.a.c.Call                             : Exception:

注：仅粘贴异常开头部分，完整信息非常冗长。

当前日志配置 #

生产环境日志配置：

logging.level.root=error

相关代码 #

引发问题的方法（最初版本）：

private void myCustomFunction(String value) {
    try {
        Balance[] balances = service.getNetBalance(value);
    } catch (Exception ignored) {}
}

getNetBalance方法会抛出RemoteException，无需处理该异常。

修改后尝试捕获RemoteException并自定义日志：

private void myCustomFunction(String value) {
    try {
        Balance[] balances = service.getNetBalance(value);
    } catch (RemoteException e) {
        log.error(e.getMessage())
    }
}

修改后能看到自定义日志，但org.xml.sax.SAXException的栈日志仍会输出，占用大量日志空间。

排查与尝试 #

曾尝试添加日志配置关闭相关输出，但未解决问题：

logging.level.org.xml.sax=off

经排查，抛出org.xml.sax.SAXException: Bad types的是org.apache.axis.message包下的RPCHandler类，相关代码片段：

if (null != xsiClass  && !JavaUtils.isConvertable(xsiClass, destClass)) {
           throw new SAXException("Bad types (" +
                                  xsiClass + " -> " + destClass + ")");
}

核心诉求 #

如何关闭该SAXException的栈日志输出，避免其打印到控制台？
