Spring 消耗 soap web 服务，wsdl 问题

Question

I'm trying to create rest api that connects with third party soap web service. I'm using maven jaxb2 plugin to generate classes based on wsdl. When i run application no code is created. There's no error either. Exception is seen directly in pom file where execution is marked red. Url works fine, i can access it via browser and wsdl shows up. Could you help?

              <plugin>
                    <groupId>org.jvnet.jaxb2.maven2</groupId>
                    <artifactId>maven-jaxb2-plugin</artifactId>
                    <executions>
                        <execution>
                            <goals>
                                <goal>generate</goal>
                            </goals>
                        </execution>
                    </executions>
                    <configuration>
                        <schemaLanguage>WSDL</schemaLanguage>
                        <generatePackage>com.app.pack</generatePackage>
                        <generateDirectory>${project.basedir}/src/main/java</generateDirectory>
                        <forceRegenerate>true</forceRegenerate>                     
                        <schemas>
                            <schema>
                                <url>someurl</url>
                            </schema>
                        </schemas>
                    </configuration>
            </plugin>

When I hover execution(in pom.xml) I can see error:

org.apache.maven.plugin.PluginExecutionException: Execution default of goal org.jvnet.jaxb2.maven2:maven-jaxb2-plugin:0.14.0:generate failed.

UPDATE

I realised problem was with wsdl protected with ssl. I created keystore and I managed to create soapui project with it. When i try to add keystore to maven plugin it doesn't work and same exception pops out. I tried with codegen as well and i have some problems with wsdl file, so I'd rather use url.

              <plugin> 
                <groupId>org.jvnet.jaxb2.maven2</groupId>
                <artifactId>maven-jaxb2-plugin</artifactId>
                <version>0.14.0</version>
                <executions>
                     <execution>
                          <goals>
                              <goal>generate</goal>
                          </goals>
                     </execution>
                </executions>
                <configuration>
                      <schemaLanguage>WSDL</schemaLanguage>
                      <generateDirectory>${project.basedir}/src/main/java</generateDirectory>
                      <generatePackage>com.generated</generatePackage>
                      <schemas>
                            <schema>ssl url</url>
                            </schema>
                      </schemas>
                      <properties>
                            <property>
                              <name>javax.net.ssl.trustStore</name>
                              <value>${project.basedir}/src/main/resources/newkeystore2.jks</value>
                            </property>
                            <property>
                              <name>javax.net.ssl.trustStorePassword</name>
                              <value>pass</value>
                            </property>
                          </properties>
                </configuration>                
            </plugin>   

So how should I properly add keystore to plugin?

Answer 1

One workaround is to use Soap UI to create the Java Classes.

In my case it worked.

The correct option is shown here (Tools -> Axis 2 Artifacts)

Hope it can be usefull.

Answer 2

It's a Spring project, probably you have Spring Tool Suite IDE, in this case you why don't use Apache cxf Plugin? this plugin comes integrated in Spring libraries.

Just put this dependency:

<dependency>
    <groupId>org.apache.cxf</groupId>
    <artifactId>cxf-spring-boot-starter-jaxws</artifactId>
    <version>3.2.5</version>
</dependency>

In the build section:

    <plugin>
        <groupId>org.apache.cxf</groupId>
        <artifactId>cxf-codegen-plugin</artifactId>
        <version>${cxf.version}</version>
        <executions>
            <execution>
                <id>generate-sources</id>
                <phase>generate-sources</phase>
                <configuration>
                    <sourceRoot>${basedir}/src/generated</sourceRoot>
                    <wsdlOptions>
                        <wsdlOption>
                            <wsdl>${basedir}/src/main/resources/wsdl/Service.wsdl</wsdl>
                                <wsdlLocation>classpath:wsdl/Service.wsdl</wsdlLocation>
                            </wsdlOption>
                    </wsdlOptions>
                </configuration>
                <goals>
                    <goal>wsdl2java</goal>
                </goals>
            </execution>
        </executions>
    </plugin>

You must have a copy of wsdl file in "/src/main/resources/wsdl" location

Answer 3

Try by adding autoNameResolution in configuration like as shown below:

<configuration>
  <args>
   <arg>-XautoNameResolution</arg>
  </args>
 
 .....
</configuration>
