一、前言

上一篇已经完整的描述了spring boot 与cxf整合工程，包括服务端的发布以及客户端的访问。但是整个日志输出只有一个简单的一句：

o.a.c.w.s.f.ReflectionServiceFactoryBean : Creating Service {http://ws.cxf.ouyushan.org/}UserServiceService from class org.ouyushan.cxf.ws.UserService

表示通过CXF已创建指定服务。但是webservice服务中设计的请求信息一星半点都没有，当服务出现问题时，如何通过获取日志来分析问题呢？

其实在CXF整合完成后，其它附加的高级功能基本上都是通过拦截器来实现的。日志捕获和输出也是基于此实现的。

本文将带领大家快速实现CXF日志输出功能。

项目源码： https://github.com/ouyushan/spring-webservice-samples

spring-cxf参考源码： https://github.com/code-not-found/cxf-jaxws

spring-ws参考源码： https://github.com/code-not-found/spring-ws

二、开发环境

IDE:：IDEA

JDK：1.8

maven：3.6.2

spring boot：2.4.0

cxf：3.4.1

三、实现步骤

具体代码实现步骤和上篇一样。本章在之前基础上讲解新增内容。

3.1、实现服务端和客户端

新建服务端和客户端spring-cxf-client-logging、spring-cxf-server-logging，并完成服务部署和客户端访问接口，具体步骤见上一篇。

3.2、添加日志输出依赖

spring boot与cxf整合后输出业务日志只需引入cxf-rt-features-logging，并实现日志拦截器即可。

服务端、客服端pom文件中添加cxf日志依赖包

<dependency>
    <groupId>org.apache.cxf</groupId>
    <artifactId>cxf-rt-features-logging</artifactId>
    <version>3.4.1</version>
</dependency>

3.3、实现日志输出拦截器

在服务端和客户端配置类中，添加请求接入和响应输出日志拦截器

@Bean
public LoggingInInterceptor loggingInInterceptor() {
    return new LoggingInInterceptor();
}

@Bean
public LoggingOutInterceptor loggingOutInterceptor() {
    return new LoggingOutInterceptor();
}

服务端在Endpoint中配置新增的拦截器

// log the request and response messages
endpoint.getInInterceptors()
        .add(loggingInInterceptor());
endpoint.getOutInterceptors()
        .add(loggingOutInterceptor());

客户端在UserService中配置新增的拦截器

// log the request and response messages
jaxWsProxyFactoryBean.getInInterceptors()
        .add(loggingInInterceptor());
jaxWsProxyFactoryBean.getOutInterceptors()
        .add(loggingOutInterceptor());

3.4、功能验证

分别启动服务端和客户端，访问客户端请求接口：

http://localhost:7070/user/get?userId=1

客户端控制台输出如下：

2020-11-26 20:22:00.884  INFO 8768 --- [nio-7070-exec-1] o.a.cxf.services.UserService.REQ_OUT     : REQ_OUT
    Address: http://localhost:8080/ws/user
    HttpMethod: POST

    ExchangeId: 3140c6ed-a420-4dee-b970-4f9452b17d17

    Payload: <soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/"><soap:Body><ns2:getUserName xmlns:ns2="http://ws.cxf.ouyushan.org/"><userId>1</userId></ns2:getUserName></soap:Body></soap:Envelope>

2020-11-26 20:22:01.272  INFO 8768 --- [nio-7070-exec-1] o.a.cxf.services.UserService.RESP_IN     : RESP_IN
    Address: http://localhost:8080/ws/user
    Content-Type: text/xml;charset=UTF-8
    ResponseCode: 200
    ExchangeId: 3140c6ed-a420-4dee-b970-4f9452b17d17
    ServiceName: UserServiceService
    PortName: UserServicePort
    PortTypeName: UserService
    Headers: {Keep-Alive=timeout=60, connection=keep-alive, content-type=text/xml;charset=UTF-8, Content-Length=220, Date=Thu, 26 Nov 2020 12:22:01 GMT}
    Payload: <soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/"><soap:Body><ns2:getUserNameResponse xmlns:ns2="http://ws.cxf.ouyushan.org/"><return>tom</return></ns2:getUserNameResponse></soap:Body></soap:Envelope>

服务端控制台输出如下：

2020-11-26 20:22:01.057  INFO 10604 --- [nio-8080-exec-4] o.a.cxf.services.UserService.REQ_IN      : REQ_IN

    Payload: <soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/"><soap:Body><ns2:getUserName xmlns:ns2="http://ws.cxf.ouyushan.org/"><userId>1</userId></ns2:getUserName></soap:Body></soap:Envelope>

2020-11-26 20:22:01.108  INFO 10604 --- [nio-8080-exec-4] o.a.cxf.services.UserService.RESP_OUT    : RESP_OUT

    ResponseCode: 200
    ExchangeId: 3a1a8ecf-f857-4472-9f56-165b54144dae

从日志可以看出完整的请求链路信息
