如何使用自定义消息将soap请求和响应记录到Spring Boot中的文件？

import org.springframework.ws.context.MessageContext;
import org.springframework.ws.server.EndpointInterceptor;

public class CustomLoggingInterceptor implements EndpointInterceptor {

    @Override
    public boolean handleRequest(MessageContext messageContext, Object endpoint) throws Exception {
        // 获取SOAP请求内容，并记录到文件中
        String request = messageContext.getRequest().toString();
        // 将request写入文件
        // ...
        return true;
    }

    @Override
    public boolean handleResponse(MessageContext messageContext, Object endpoint) throws Exception {
        // 获取SOAP响应内容，并记录到文件中
        String response = messageContext.getResponse().toString();
        // 将response写入文件
        // ...
        return true;
    }

    // 其他方法省略
}

import org.springframework.context.annotation.Configuration;
import org.springframework.ws.config.annotation.EnableWs;
import org.springframework.ws.config.annotation.WsConfigurerAdapter;
import org.springframework.ws.server.EndpointInterceptor;

@Configuration
@EnableWs
public class WebServiceConfig extends WsConfigurerAdapter {

    @Override
    public void addInterceptors(List<EndpointInterceptor> interceptors) {
        interceptors.add(new CustomLoggingInterceptor());
    }
}
