Booking Server (REST) Skeleton for Java

This ia a reference implementation for API v3 Booking server based on:

Prerequisites

Require installations of

Get Started

  1. Copy the Proto Interface into a proto file (api_v3.proto). Modify the package to match your project (com.partner.mapsbooking.v3.model).

  2. Create a web application project in your IDE named booking_server_v3, add Maven support to this project.

  3. Place your proto file under the src/main/resources, add dependencies for Jersey and protocol buffers runtime to the Maven pom.xml file:

         <dependencyManagement>
             <dependencies>
                 <dependency>
                     <groupId>org.glassfish.jersey</groupId>
                     <artifactId>jersey-bom</artifactId>
                     <version>${jersey.version}</version>
                     <type>pom</type>
                     <scope>import</scope>
                 </dependency>
             </dependencies>
         </dependencyManagement>
    
         <dependencies>
             <dependency>
                 <groupId>org.glassfish.jersey.containers</groupId>
                 <artifactId>jersey-container-servlet-core</artifactId>
             </dependency>
             <dependency>
                 <groupId>org.glassfish.jersey.media</groupId>
                 <artifactId>jersey-media-json-jackson</artifactId>
                 <version>2.27</version>
             </dependency>
             <dependency>
                 <groupId>com.google.protobuf</groupId>
                 <artifactId>protobuf-java</artifactId>
                 <version>3.5.1</version>
             </dependency>
             <dependency>
                 <groupId>io.grpc</groupId>
                 <artifactId>grpc-protobuf</artifactId>
                 <version>1.11.0</version>
             </dependency>
         </dependencies>
    
         <properties>
             <java.version>1.8</java.version>
             <jersey.version>2.23.2</jersey.version>
         </properties>
    
  4. Execute the following command under src/main to auto-generate a source file for the classes defined in the proto file:

     protoc --java_out=java resources/api_v3.proto
    
  5. Inside of the src/main/java, create a new package matching your groupId (com.partner.mapsbooking). Retrieve the sample code from the repo:

     git clone https://maps-booking.googlesource.com/java-maps-booking-rest-server-v3-skeleton
    

    place the files under your package, follow the TODOs to complete your implementation.

  6. Configure your servlet by modifying the web.xml file:

    <?xml version="1.0" encoding="UTF-8"?>
    <web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee"
             xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
             xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_4_0.xsd"
             version="4.0">
    
        <servlet>
            <servlet-name>Booking Rest Server</servlet-name>
            <servlet-class>org.glassfish.jersey.servlet.ServletContainer</servlet-class>
            <init-param>
                <param-name>jersey.config.server.provider.packages</param-name>
                <param-value>com.partner.mapsbooking</param-value>
            </init-param>
            <load-on-startup>1</load-on-startup>
        </servlet>
    
        <servlet-mapping>
            <servlet-name>Booking Rest Server</servlet-name>
            <url-pattern>/mapsbooking/*</url-pattern>
        </servlet-mapping>
    </web-app>
    
  7. In the Run Configurations, set up a Tomcat server configuration. Add all the jars to the /WEB_INF/lib directory (project structure -> artifacts -> After selecting all jars right click and choose “Put into /WEB-INF/lib”).

  8. Run Tomcat to start your server.
