SpringBoot 整合WebService

在Spring Boot中整合WebService，可以使用Spring Web Services和JAX-WS。以下是一个简单的例子，展示如何使用Spring Boot整合一个SOAP WebService。

1. 添加依赖到你的pom.xml：

<dependencies>
    <!-- Spring Boot Web Services Starter -->
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-web-services</artifactId>
    </dependency>
    <!-- SOAP WebService 客户端 -->
    <dependency>
        <groupId>org.apache.cxf</groupId>
        <artifactId>cxf-rt-frontend-jaxws</artifactId>
        <version>3.4.4</version>
    </dependency>
</dependencies>

2. 创建一个客户端接口，用来生成WebService代理类：

import javax.jws.WebService;
 
@WebService(targetNamespace = "http://www.example.com/webservice")
public interface MyWebService {
    String getData(String input);
}

3. 配置客户端：

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.apache.cxf.jaxws.JaxWsProxyFactoryBean;
 
@Configuration
public class WebServiceClientConfig {
 
    @Bean
    public MyWebService myWebService() {
        JaxWsProxyFactoryBean factory = new JaxWsProxyFactoryBean();
        factory.setServiceClass(MyWebService.class);
        factory.setAddress("http://www.example.com/webservice");
        return (MyWebService) factory.create();
    }
}

4. 使用客户端：

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
 
@Service
public class MyService {
 
    private final MyWebService myWebService;
 
    @Autowired
    public MyService(MyWebService myWebService) {
        this.myWebService = myWebService;
    }
 
    public String callWebService(String input) {
        return myWebService.getData(input);
    }
}

5. 启动类：

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
 
@SpringBootApplication
public class WebServiceClientApplication {
 
    public static void main(String[] args) {
        SpringApplication.run(WebServiceClientApplication.class, args);
    }
}

以上代码展示了如何在Spring Boot应用程序中创建一个SOAP WebService客户端。你需要替换MyWebService接口和myWebService()方法中的地址为实际WebService的URL，以及调整@WebService注解中的targetNamespace为实际WebService的命名空间。
