来一个HelloWorld，SpringBoot发布WebService可简单啦。

步骤 1 搭建项目

请参照这个教程搭建一个SpringBoot项目，注意，项目名字换成webService

步骤 2 配置pom.xml

<dependency>
    <groupId>org.apache.cxf</groupId>
    <artifactId>cxf-rt-frontend-jaxws</artifactId>
    <version>3.1.6</version>
</dependency>

<dependency>
    <groupId>org.apache.cxf</groupId>
    <artifactId>cxf-rt-transports-http</artifactId>
    <version>3.1.6</version>
</dependency>

加上这两个jar包。

步骤 3 建services服务包

步骤 4 登陆接口类

设置一个登陆接口类

image

package com.webservice.demo.services;
import javax.jws.WebService;
import java.util.Map;

@WebService(name = "LoginService",              // 暴露服务名称
        targetNamespace = "http://java18.cn"    // 命名空间
)
public interface LoginService {

    Map<String,Object> userLogin();

}

步骤 5 登陆接口实现类

image

image

package com.webservice.demo.services.impl;

import com.webservice.demo.services.LoginService;

import javax.jws.WebService;
import java.util.HashMap;
import java.util.Map;

@WebService(serviceName = "LoginService", // 与接口中指定的name一致
        targetNamespace = "http://java18.cn", // 与接口中的命名空间一致
        endpointInterface = "com.webservice.demo.services.LoginService"// 接口地址
)
public class LoginServiceImpl implements LoginService {

    @Override
    public Map<String, Object> userLogin() {
        Map<String, Object> resultMap = new HashMap<>();
        resultMap.put("errCode",00000);
        resultMap.put("errMsg",null);
        return resultMap;
    }
}

步骤 6 创建CXF配置类

image

package com.webservice.demo.config;

import com.webservice.demo.services.LoginService;
import com.webservice.demo.services.impl.LoginServiceImpl;
import org.apache.cxf.Bus;
import org.apache.cxf.bus.spring.SpringBus;
import org.apache.cxf.jaxws.EndpointImpl;
import org.apache.cxf.transport.servlet.CXFServlet;
import org.springframework.boot.web.servlet.ServletRegistrationBean;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import javax.xml.ws.Endpoint;

@Configuration
public class CxfConfig {

    @Bean
    public ServletRegistrationBean dispatcherServlet() {
        return new ServletRegistrationBean(new CXFServlet(),"/webservice/*");
    }

    @Bean(name = Bus.DEFAULT_BUS_ID)
    public SpringBus springBus() {
        return new SpringBus();
    }

    @Bean
    public LoginService loginService() {
        return new LoginServiceImpl();
    }

    @Bean
    public Endpoint endpoint() {
        EndpointImpl endpoint = new EndpointImpl(springBus(), loginService());
        endpoint.publish("/api");
        return endpoint;
    }

}

步骤 7 Parameter 0 of method errorPageCustomizer in ErrorMvcAutoConfiguration 异常解决

现在直接启动会报错的。

解决方法如下

这个方法名字换一下就好了。

步骤 8 访问webservice

启动项目，访问http://localhost:8080/webservice/api

image

步骤 9 访问wsdl

http://localhost:8080/webservice/api?wsdl
