spring boot集成web service框架教程

spring boot集成web service框架

题记： 本篇博客讲的spring boot如何集成 spring web service，如果您想用Apache CXF集成，那么可能不适合您。为什么使用spring web servce 项目地址 呢？因为spring boot存在的目的就是一个微服务框架，结果又搞个soap框架进去，显得特别不伦不类。正是因为有这么多老项目的重构才会有这么不伦不类的集成。综上，我就选了spring家族的spring web service能够很好的跟spring boot进行集成。

那么如何集成呢？我这里讲一个demo，照葫芦画瓢就行

先建一个maven 项目 
然后加入spring boot的依赖(截止目前最新是1.5.2版本)

<dependency>
      <groupId>org.springframework.boot</groupId>
      <artifactId>spring-boot-starter-web</artifactId>
      <version>1.5.2.RELEASE</version>
    </dependency>

加入spring-web-service的依赖

<dependency>
      <groupId>org.springframework.boot</groupId>
      <artifactId>spring-boot-starter-web-services</artifactId>
      <version>1.5.2.RELEASE</version>
    </dependency>

加入wsdl的依赖

<dependency>
      <groupId>wsdl4j</groupId>
      <artifactId>wsdl4j</artifactId>
      <version>1.6.3</version>
    </dependency>

所以可能完整的pom.xml是这样的

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

我们来写wsdl描述文件

<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:tns="http://www.yourcompany.com/webservice"
           targetNamespace="http://www.yourcompany.com/webservice" elementFormDefault="qualified">

    <xs:element name="getCountryRequest">
        <xs:complexType>
            <xs:sequence>
                <xs:element name="name" type="xs:string"/>
            </xs:sequence>
        </xs:complexType>
    </xs:element>

    <xs:element name="getCountryResponse">
        <xs:complexType>
            <xs:sequence>
                <xs:element name="country" type="tns:country"/>
            </xs:sequence>
        </xs:complexType>
    </xs:element>

    <xs:complexType name="country">
        <xs:sequence>
            <xs:element name="name" type="xs:string"/>
            <xs:element name="population" type="xs:int"/>
            <xs:element name="capital" type="xs:string"/>
            <xs:element name="currency" type="tns:currency"/>
        </xs:sequence>
    </xs:complexType>

    <xs:simpleType name="currency">
        <xs:restriction base="xs:string">
            <xs:enumeration value="GBP"/>
            <xs:enumeration value="EUR"/>
            <xs:enumeration value="PLN"/>
        </xs:restriction>
    </xs:simpleType>
</xs:schema>

具体的应该怎么写，请看下官方文档这里

然后用工具生成实体类，这里比较关键

对coruntries.xds右键，然后选中web service那一项，generate java code from xml schema using jaxb

选生成代码的地方。OK

然后编写webserviceconfig文件，指定url什么的。

package com.itar.ws.config;

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.ws.config.annotation.EnableWs;
import org.springframework.ws.config.annotation.WsConfigurerAdapter;
import org.springframework.ws.transport.http.MessageDispatcherServlet;
import org.springframework.ws.wsdl.wsdl11.DefaultWsdl11Definition;
import org.springframework.xml.xsd.SimpleXsdSchema;
import org.springframework.xml.xsd.XsdSchema;

@EnableWs
@Configuration
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 = "countries")
    public DefaultWsdl11Definition defaultWsdl11Definition(XsdSchema countriesSchema) {
        DefaultWsdl11Definition wsdl11Definition = new DefaultWsdl11Definition();
        wsdl11Definition.setPortTypeName("CountriesPort");
        wsdl11Definition.setLocationUri("/ws");
        wsdl11Definition.setTargetNamespace("http://www.yourcompany.com/webservice");
        wsdl11Definition.setSchema(countriesSchema);
        return wsdl11Definition;
    }

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

然后编写endpoint，类似于controller，然后我就丢在controller里面了

package com.itar.ws.controller;

import com.itar.ws.model.GetCountryRequest;
import com.itar.ws.model.GetCountryResponse;
import com.itar.ws.service.CountryRepository;
import org.springframework.beans.factory.annotation.Autowired;
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;

@Endpoint
public class CountryEndpoint {
    private static final String NAMESPACE_URI = "http://www.yourcompany.com/webservice";

    private CountryRepository countryRepository;

    @Autowired
    public CountryEndpoint(CountryRepository countryRepository) {
        this.countryRepository = countryRepository;
    }

    @PayloadRoot(namespace = NAMESPACE_URI, localPart = "getCountryRequest")
    @ResponsePayload
    public GetCountryResponse getCountry(@RequestPayload GetCountryRequest request) {
        GetCountryResponse response = new GetCountryResponse();
        response.setCountry(countryRepository.findCountry(request.getName()));

        return response;
    }
}

然后写spring boot启动文件

package com.itar.ws;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
public class Application {

    public static void main(String[] args) {
        SpringApplication.run(Application.class, args);
    }
}

启动即可

访问这个http://localhost:8080/ws/countries.wsdl 可以看到项目启动成功

请求

这是body里面的，用post

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/"
                  xmlns:gs="http://www.yourcompany.com/webservice">
   <soapenv:Header/>
   <soapenv:Body>
      <gs:getCountryRequest>
         <gs:name>Spain</gs:name>
      </gs:getCountryRequest>
   </soapenv:Body>
</soapenv:Envelope>

提问时间 
1. 我要改request里面某些字段名称怎么办？

可以在生成的实体文件里面，用注解XMLElement里面的一个属性name来标识

1. response也是一样的做法
