springboot实现WebService接口

在Spring Boot中实现WebService接口，通常可以使用Spring Web Services项目。以下是一个简单的例子，展示如何使用Spring Boot创建一个简单的SOAP服务端。

1. 首先，创建一个Maven项目并添加Spring Boot和Spring Web Services依赖。

<dependencies>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-web-services</artifactId>
    </dependency>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-test</artifactId>
        <scope>test</scope>
    </dependency>
    <dependency>
        <groupId>org.springframework.ws</groupId>
        <artifactId>spring-ws-test</artifactId>
        <scope>test</scope>
    </dependency>
</dependencies>

2. 创建一个WebService接口和一个实现类。

import org.springframework.stereotype.Component;
import org.springframework.ws.server.endpoint.annotation.Endpoint;
import org.springframework.ws.server.endpoint.annotation.PayloadRoot;
import org.springframework.ws.server.endpoint.annotation.RequestPayload;
import org.springframework.ws.server.endpoint.annotation.ResponsePayload;
import org.springframework.xml.transform.TransformerObjectSupport;
 
@Endpoint
public class MyWebServiceEndpoint extends TransformerObjectSupport {
 
    private static final String NAMESPACE_URI = "http://www.example.com/webservice";
 
    @PayloadRoot(namespace = NAMESPACE_URI, localPart = "MyRequest")
    @ResponsePayload
    public MyResponse handleMyRequest(@RequestPayload MyRequest request) {
        // 实现处理请求的逻辑
        MyResponse response = new MyResponse();
        // 设置响应数据
        return response;
    }
}

3. 配置Spring Boot应用。

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

4. 创建请求和响应对象的XML映射。

<!-- MyRequest.xml -->
<xsd:element name="MyRequest">
    <xsd:complexType>
        <xsd:sequence>
            <xsd:element name="requestParameter" type="xsd:string"/>
        </xsd:sequence>
    </xsd:complexType>
</xsd:element>
 
<!-- MyResponse.xml -->
<xsd:element name="MyResponse">
    <xsd:complexType>
        <xsd:sequence>
            <xsd:element name="responseParameter" type="xsd:string"/>
        </xsd:sequence>
    </xsd:complexType>
