 <h1 id="develop-microservice-with-transparent-rpc">Develop Microservice with Transparent RPC</h1>
 <h2 id="concept-description">Concept Description</h2>
 <p>The transparent remote procedure call(RPC) development mode is a development mode based on API and API implementation. The service developer does not need to use the description of Spring MVC and JAX-RS.</p>
 <h2 id="development-example">Development Example</h2>
 <ul>
 <li><strong>Step 1</strong> Import dependencies into your maven project:</li>
 </ul>
 <p><code>xml
     &lt;dependencyManagement&gt;
      &lt;dependencies&gt;
        &lt;dependency&gt;
          &lt;groupId&gt;org.apache.servicecomb&lt;/groupId&gt;
          &lt;artifactId&gt;java-chassis-dependencies&lt;/artifactId&gt;
          &lt;version&gt;1.0.0-m1&lt;/version&gt;
          &lt;type&gt;pom&lt;/type&gt;
          &lt;scope&gt;import&lt;/scope&gt;
        &lt;/dependency&gt;
      &lt;/dependencies&gt;
     &lt;/dependencyManagement&gt;
     &lt;dependencies&gt;
       &lt;!--transport can optional import through endpoint setting in microservice.yaml, we import both rest and highway as example--&gt;
       &lt;dependency&gt;
         &lt;groupId&gt;org.apache.servicecomb&lt;/groupId&gt;
         &lt;artifactId&gt;transport-rest-vertx&lt;/artifactId&gt;
       &lt;/dependency&gt;
       &lt;dependency&gt;
         &lt;groupId&gt;org.apache.servicecomb&lt;/groupId&gt;
         &lt;artifactId&gt;transport-highway&lt;/artifactId&gt;
       &lt;/dependency&gt;
       &lt;dependency&gt;
         &lt;groupId&gt;org.apache.servicecomb&lt;/groupId&gt;
         &lt;artifactId&gt;provider-pojo&lt;/artifactId&gt;
       &lt;/dependency&gt;
       &lt;dependency&gt;
         &lt;groupId&gt;org.slf4j&lt;/groupId&gt;
         &lt;artifactId&gt;slf4j-log4j12&lt;/artifactId&gt;
       &lt;/dependency&gt;
     &lt;/dependencies&gt;</code></p>
 <ul>
 <li><strong>Step 2</strong> Define a service API. Compile the Java API definition based on the API definition defined before development. The code is as follows:</li>
 </ul>
 <p><code>java
    public interface Hello {
      String sayHi(String name);
      String sayHello(Person person);
    }</code></p>
 <ul>
 <li><strong>Step 3</strong> implement the service. The implementation of the Hello service is as follows:</li>
 </ul>
 <p>```java
    import org.apache.servicecomb.samples.common.schema.Hello;
    import org.apache.servicecomb.samples.common.schema.models.Person;</p>
 <p>public class HelloImpl implements Hello {
      @Override
      public String sayHi(String name) {
        return "Hello " + name;
      }</p>
 <pre><code> @Override
  public String sayHello(Person person) {
    return "Hello person " + person.getName();
  }
 </code></pre>
 <p>}
    ```</p>
 <ul>
 <li><strong>Step 4</strong> Release the service.
    The transparent RPC development mode supports two service release mode: Spring XML configuration and Annotation configuration:</li>
 <li>Spring XML configuration Mode:
    Create the pojoHello.bean.xml file in the resources/META-INF/spring directory and declare the schema in the file. The content of the file is as follows:</li>
 </ul>
 <p>```xml
    <?xml version="1.0" encoding="UTF-8"?></p>
 <p><beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
           xmlns:p="http://www.springframework.org/schema/p" xmlns:util="http://www.springframework.org/schema/util"
           xmlns:cse="http://www.huawei.com/schema/paas/cse/rpc"
           xmlns:context="http://www.springframework.org/schema/context"
           xsi:schemaLocation="http://www.springframework.org/schema/beans classpath:org/springframework/beans/factory/xml/spring-beans-3.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd http://www.huawei.com/schema/paas/cse/rpc classpath:META-INF/spring/spring-paas-cse-rpc.xsd"></p>
 <pre><code>   &lt;cse:rpc-schema schema-id="pojoHello" implementation="org.apache.servicecomb.samples.pojo.provider.PojoHelloImpl"/&gt;
 </code></pre>
 <p></beans>
    ```</p>
 <ol>
 <li>Annotation configuration Mode:
    @RpcSchema is used to define schema during the API Hello implementation. The code is as follows:</li>
 </ol>
 <p>```java
    import org.apache.servicecomb.provider.pojo.RpcSchema;
    @RpcSchema(schemaId = "pojoHello")
    public class HelloImpl implements Hello {
       @Override
       public String sayHi(String name) {
         return "Hello " + name;
       }</p>
 <pre><code>  @Override
   public String sayHello(Person person) {
     return "Hello person " + person.getName();
   }
 </code></pre>
 <p>}
    ```</p>
 <p>In the pojoHello.bean.xml file of resources/META-INF/spring directory, configure base-package that performs scanning. The content of the file is as follows:</p>
 <p>```xml
    <?xml version="1.0" encoding="UTF-8"?></p>
 <p><beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
           xmlns:p="http://www.springframework.org/schema/p" xmlns:util="http://www.springframework.org/schema/util"
           xmlns:cse="http://www.huawei.com/schema/paas/cse/rpc"
           xmlns:context="http://www.springframework.org/schema/context"
           xsi:schemaLocation="http://www.springframework.org/schema/beans classpath:org/springframework/beans/factory/xml/spring-beans-3.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd http://www.huawei.com/schema/paas/cse/rpc classpath:META-INF/spring/spring-paas-cse-rpc.xsd"></p>
 <pre><code>   &lt;context:component-scan base-package="org.apache.servicecomb.samples.pojo.provider"/&gt;
 </code></pre>
 <p></beans>
    ```</p>
 <p><strong>Note: THE PATH FOR RPC IS <code>ClassName/MethodName</code>, AND THE METHOD IS <code>POST</code>.</strong></p>
 <p>In this sample the Path of sayHi is <code>/HelloImpl/sayHi</code>, and the Path of sayHello is <code>/HelloImpl/sayHello</code>.</p>
 <blockquote>
 <p><strong>NOTE</strong>：
 Different from the Spring MVC and JAX-RS development modes, the transparent RPC development mode used <code>@RpcSchema</code> instead of <code>@RestSchema</code>.</p>
 </blockquote>
 <ul>
 <li><strong>Step 5</strong> Add service definition file:</li>
 </ul>
 <p>Add <a href="http://servicecomb.incubator.apache.org/cn/users/service-definition/">microservice.yaml</a> file into resources folder of your project.</p>
 <ul>
 <li><strong>Step 6</strong> Add Main class:</li>
 </ul>
 <p>```java
    import org.apache.servicecomb.foundation.common.utils.BeanUtils;
    import org.apache.servicecomb.foundation.common.utils.Log4jUtils;</p>
 <p>public class Application {
      public static void main(String[] args) throws Exception {
         //initializing log, loading bean(including its parameters), and registering service, more detail can be found here : http://servicecomb.incubator.apache.org/users/application-boot-process/
         Log4jUtils.init();
         BeanUtils.init();
      }
    }
    ```</p>
