Springboot注解开发WebService

本项目使用IDEA开发，Eclipse同理

一、项目初始化

打开IDEA，选择Spring boot生成器，填写项目相关信息

注意：若需要使用jdk8，服务器URL需要更换为start.aliyun.com

本文编辑时，start.spring.io要求jdk最低版本为：17

jdk版本不同，所需依赖版本也有所不同

下一步，勾选Spring Web Service

自jdk1.8之后，javax.* 被调整为：jakarta .*，请参考 cxf 4.0 说明：

Apache CXF -- 4.0 Migration Guide

jdk1.8 pom.xml文件依赖如下：

<dependencies>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-web-services</artifactId>
    </dependency>
    <dependency>
        <groupId>org.apache.cxf</groupId>
        <artifactId>cxf-spring-boot-starter-jaxws</artifactId>
        <version>3.2.7</version>
    </dependency>
    <dependency>
        <groupId>org.hibernate</groupId>
        <artifactId>hibernate-validator</artifactId>
        <version>6.0.18.Final</version>
    </dependency>

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

jdk17 pom.xml文件依赖如下：

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

    <dependency>
        <groupId>org.apache.cxf</groupId>
        <artifactId>cxf-spring-boot-starter-jaxws</artifactId>
        <version>4.0.4</version>
    </dependency>
    <dependency>
        <groupId>org.hibernate</groupId>
        <artifactId>hibernate-validator</artifactId>
        <version>8.0.1.Final</version>
    </dependency>

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

二、添加接口

一个接口类可以写多个方法

package top.braycep.ws;

import javax.jws.WebMethod;
import javax.jws.WebService;

@WebService
public interface EndpointDemo {
    @WebMethod
    String doBiz(String request);
}

三、添加实现

此处REQUEST_RAW_CONTENT来源于拦截器中提取的原始请求报文，并非自带属性

package top.braycep.ws.impl;

import org.springframework.stereotype.Component;
import top.braycep.ws.EndpointDemo;

import javax.annotation.Resource;
import javax.xml.ws.WebServiceContext;

@Component
public class EndpointDemoImpl implements EndpointDemo {
    @Resource
    private WebServiceContext webServiceContext;

    @Override
    public String doBiz(String request) {
        Object rawContent = webServiceContext.getMessageContext().get("REQUEST_RAW_CONTENT");
        if (rawContent instanceof String && !((String) rawContent).isEmpty()) {
            System.out.println(rawContent);
        }

        return "doBiz By EndpointDemoImpl";
    }
}

四、发布服务

多个接口服务类，每个都需要注册

package top.braycep.ws.config;

import org.apache.cxf.Bus;
import org.apache.cxf.jaxws.EndpointImpl;
import org.apache.cxf.jaxws.JaxWsServerFactoryBean;
import org.apache.cxf.transport.servlet.CXFServlet;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Qualifier;
import org.springframework.boot.web.servlet.ServletRegistrationBean;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import top.braycep.ws.EndpointDemo;

import javax.xml.ws.Endpoint;

@Configuration
public class WSConfig {

    @Autowired
    private EndpointDemo endpointDemo;

    @Autowired
    @Qualifier(Bus.DEFAULT_BUS_ID)
    public Bus bus;

    @Bean
    public ServletRegistrationBean<CXFServlet> servletServletRegistrationBean() {
        return new ServletRegistrationBean<>(new CXFServlet(), "/ws/*");
    }

    // 发布服务
    @Bean
    public Endpoint endpointDemo() {
        EndpointImpl endpoint = new EndpointImpl(bus, endpointDemo);
        endpoint.publish("/endpointDemo");
        return endpoint;
    }
}

另一种发布方式

// 方式一
@Bean
public Endpoint endpointDemo1() {
    EndpointImpl endpoint = new EndpointImpl(bus, endpointDemo);
    // 内部会调用 bean.create();
    endpoint.publish("/endpointDemo");
    return endpoint;
}

// 方式二
@Bean
public JaxWsServerFactoryBean endpointDemo2() {
    JaxWsServerFactoryBean bean = new JaxWsServerFactoryBean();
    bean.setAddress("/endpointDemo");
    bean.setServiceClass(EndpointDemoImpl.class);
    bean.setServiceBean(endpointDemo);
    bean.setBus(bus);
    // 必需
    bean.create();
    return bean;
}
