Question

我正在使用spring soap实现开发一个web服务，因此我的服务类使用@Endpoint注释进行注释。现在，我想将SPRING AOP用于我已经实现的应用程序日志记录。但是，正如我已经注意到的那样，直到我从切入点表达式中执行我的服务类，在调用我的webservice时，我得不到端点映射发现的异常。当我从AOP的范围中排除服务类时，事情再次正常工作。有什么想法吗？

更新

我的记录器类

package com.cps.arch.logging;

@Component
@Aspect
public class LoggerAspect {

    private static final Logger logger = LoggerFactory.getLogger("Centralized Payment System");

    @Before("(execution(* com.cps..*.*(..)) and not execution(* com.cps.service..*.*(..)))")
    public void logBefore(JoinPoint joinPoint) {

        logger.info("Execution Start : "+"Class: "+joinPoint.getTarget().getClass().getName()+
                "Method: "+joinPoint.getSignature().getName());
    }

}

我的服务端点：

package com.cps.service.impl;

@Endpoint
public class EndpointIntegrationServiceImpl  implements EndpointIntegrationService
{
    private static final String NAMESPACE_URI = "http://www.example.com/cps/model";

    @Autowired
    public MYBO myBO ;

    @PayloadRoot(namespace = NAMESPACE_URI, localPart = "SaveDataRequest")
    public void saveData(@RequestPayload
            SaveDataRequest data) {
        //business layer invocation
    }
}

我的WS配置

@EnableWs
@Configuration
@ComponentScan(basePackages={"com.cps"})
public class WebServiceConfig extends WsConfigurerAdapter
{

    @Bean
    public ServletRegistrationBean messageDispatcherServlet(ApplicationContext applicationContext) {
        MessageDispatcherServlet servlet = new MessageDispatcherServlet();
        servlet.setApplicationContext(applicationContext);
        servlet.setTransformWsdlLocations(true);
        return new ServletRegistrationBean(servlet, "/ws/*");
    }

    @Bean(name = "MyWsdl")
    public DefaultWsdl11Definition defaultWsdl11Definition(XsdSchema schema) {
        DefaultWsdl11Definition wsdl11Definition = new DefaultWsdl11Definition();
        wsdl11Definition.setPortTypeName("MyPort");
        wsdl11Definition.setLocationUri("/ws");
        wsdl11Definition.setTargetNamespace("http://www.example.com/micro/payment/PaymentManagement");
        wsdl11Definition.setSchema(reconciliationSchema);
        return wsdl11Definition;
    }

    @Bean
    public XsdSchema schema() {
        return new SimpleXsdSchema(new ClassPathResource("XSD/MySchema.xsd"));
    }

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

    @Bean
    ValidationInterceptor validationInterceptor() {
            final ValidationInterceptor payloadValidatingInterceptor = new ValidationInterceptor();
            payloadValidatingInterceptor.setSchema(new ClassPathResource(
                    "XSD/MySchema.xsd"));
            return payloadValidatingInterceptor;
        }
}

很抱歉，我不得不更改一些变量/类名称以遵守公司政策。因此，您可以看到我必须将“非执行”部分放在AOP中以使我的Web服务正常工作。如果删除该部分，我会收到404错误。

Answer 1

@Tarun是对的，不过我也发现有必要延迟AppConfig config bean的初始化。

因为（@hudi）示例中的CustomValidatingInterceptor bean是EndpointInterceptor，所以在Spring初始化序列的早期需要它。这意味着它在Aop编织config bean之前已经实例化了。请注意原始问题中如何EndpointInterceptor。

避免这种情况的一种方法是使用ObjectFactory。这可以从一开始就接通，但是允许Spring延迟config bean的实际实例化，直到拦截器和Aop代理都被很好地初始化为止。

在your question上有一个这样的例子。这次测试来自SoapUI。

以下是您分享的代码

package org.example;

import java.util.List;

import org.aspect.PersistentAspect;
import org.springframework.aop.support.AopUtils;
import org.springframework.boot.web.servlet.ServletRegistrationBean;
import org.springframework.context.ApplicationContext;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.core.io.ClassPathResource;
import org.springframework.oxm.jaxb.Jaxb2Marshaller;
import org.springframework.ws.config.annotation.EnableWs;
import org.springframework.ws.config.annotation.WsConfigurerAdapter;
import org.springframework.ws.server.EndpointInterceptor;
import org.springframework.ws.transport.http.MessageDispatcherServlet;
import org.springframework.xml.xsd.SimpleXsdSchema;
import org.springframework.xml.xsd.XsdSchema;

import javax.annotation.PostConstruct;

@Configuration
@EnableWs
public class WsConfig extends WsConfigurerAdapter {

    @Bean
    public ServletRegistrationBean messageDispatcherServlet(ApplicationContext applicationContext) {
        final MessageDispatcherServlet servlet = new MessageDispatcherServlet();
        servlet.setApplicationContext(applicationContext);
        servlet.setTransformWsdlLocations(true);
        return new ServletRegistrationBean(servlet, "/v1/*");
    }

    @Bean
    public XsdSchema schema() {
        return new SimpleXsdSchema(new ClassPathResource("country.xsd"));
    }

    @Bean
    public Jaxb2Marshaller marshaller() {
        Jaxb2Marshaller marshaller = new Jaxb2Marshaller();
        String[] jaxbContext = new String[] { "io.spring.guides.gs_producing_web_service" };
        marshaller.setContextPaths(jaxbContext);
        return marshaller;
    }

    @Override
    public void addInterceptors(List<EndpointInterceptor> interceptors) {
        // aop not working
        //interceptors.add(new CustomValidatingInterceptor(schema(), config()));
        System.out.println("Loading addInterceptors");
        interceptors.add(new CustomValidatingInterceptor(schema(), null));
    }

    @Bean
    public AppConfig config() {
        System.out.println("Loading config Bean");

        return new AppConfig();
    }

    @PostConstruct
    @Bean
    public PersistentAspect persistentAspect() {
        System.out.println("Loading persistentAspect Bean");
        PersistentAspect persistentAspect = new PersistentAspect();

        return persistentAspect;
    }

    @Bean
    public Object testAop(AppConfig config) {
        System.out.println("is config aop proxy: " + AopUtils.isAopProxy(config));

        return config;
    }
}

你提到它不能与

一起使用

interceptors.add(new CustomValidatingInterceptor(schema(), config()));

但可以使用

interceptors.add(new CustomValidatingInterceptor(schema(), null));

手动调用config时的问题，bean由您启动而不是Spring启动，它会以某种方式干扰。您不应该使用bean方法config()来启动该类，而是使用类目录

interceptors.add(new CustomValidatingInterceptor(schema(), new AppConfig()));

它工作正常

尝试配置PayloadLoggingInterceptor

查看＆＃34; 5.5.2.1部分。 PayloadLoggingInterceptor和SoapEnvelopeLoggingInterceptor＆＃34;在Spring Reference Docs

中

使用Spring AOP的
