- Add Maven Dependencies. Open the pom.xml file and add the following dependencies: <dependency> <groupId>javax.servlet</groupId> <artifactId>servlet-api</artifactId> <version>3.0-alpha-1</version> <scope>provided</scope> </dependency> <dependency> <groupId>com.google.code.gson</groupId> <artifactId>gson</artifactId> <version>2.8.5</version> </dependency> <dependency> <groupId>org.assertj</groupId> <artifactId>assertj-core</artifactId> <version>3.11.1</version> <scope>test</scope> </dependency> <dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> <version>4.12</version> <scope>test</scope> </dependency>
- Create Model - Todo.java. Let's create a Todo model class that Servlet returns to the client as JSON: public class Todo { private Long id; private String text; public Todo() { } public Todo(Long id, String text) { this.id = id; this.text = text; } public Long getId() { return id; } public void setId(Long id) { this.id = id; } public String getText() { return text; } public void setText(String text) { this.text = text; } }
- Create Static Data - Todos.java. Let's create a Todos class that creates static data: import java.util.HashMap; import java.util.Map; public class Todos { public static Map<Long, Todo> todos = new HashMap<>(); static { todos.put(1L, new Todo(1L, "first todo")); todos.put(2L, new Todo(2L, "second todo")); } public static Long nextId() { return todos.keySet().stream().reduce(Math::max).orElse(0L) + 1L; } }
- Create Util Class. Util class to convert Stream to String: import java.io.BufferedReader; import java.io.InputStream; import java.io.InputStreamReader; import static java.util.stream.Collectors.joining; public class Util { public static String readInputStream(InputStream stream) { return new BufferedReader(new InputStreamReader(stream)).lines().collect(joining("\n")); } }
- Create Servlet - CRUD Operations. Let's create a Servlet named TodoServlet that performs CRUD operations: import com.google.gson.Gson; import com.google.gson.GsonBuilder; import javax.servlet.ServletException; import javax.servlet.http.HttpServlet; import javax.servlet.http.HttpServletRequest; import javax.servlet.http.HttpServletResponse; import java.io.BufferedReader; import java.io.IOException; import java.io.InputStream; import java.io.InputStreamReader; import static java.util.stream.Collectors.joining; public class TodoServlet extends HttpServlet { private static final Gson GSON = new GsonBuilder().create(); @Override protected void doGet(HttpServletRequest req, HttpServletResponse resp) throws IOException { String uri = req.getRequestURI(); Long id = Long.parseLong(uri.substring("/todos/".length())); String json = GSON.toJson(Todos.todos.get(id)); resp.setStatus(200); resp.setHeader("Content-Type", "application/json"); resp.getOutputStream().println(json); } @Override protected void doPost(HttpServletRequest req, HttpServletResponse resp) throws IOException { String uri = req.getRequestURI(); Long id = Long.parseLong(uri.substring("/todos/".length())); if (Todos.todos.containsKey(id)) { resp.setStatus(422); resp.getOutputStream().println("You cannot created Todo with id " + id + " because it exists!"); }
- Configure Servlet in Web.xml. Now let's configure Servlet in web.xml file: Run in this project in Tomcat server and Test all the APIs using /todosURL.
