使用 Intellij IDEA 创建基于 Jersey 和 Hibernate 的 RESETful API

介绍通过 Intellij IDEA 来创建一个 RESETful API 项目，该项目适用于基于 JavaWEB 后端技术的项目，相关技术包含 Maven、Jersey、Hibernate 等，这里不对这些技术进行过多的详细介绍，只是创建一个简单的入门项目用于学习

JDK 和 Tomcat

10.*
9.*

这里就不介绍如何安装 JDK 和 Tomcat

创建 Web Application 项目

Java JDK 将其配置成安装的版本，Tomcat 服务器也一样配置成最新的版本

点击 Next 进入一下，配置一下项目名

点击 Finish 完成，在项目名上右键 -> Add Frameworks Support 把 maven 项目的支持引入

配置 pom.xml

将以下 XML 代码复制到项目的 pom.xml 文件中，注意Intellij IDEA 生成的 pom.xml 文件无须更改，只需要将以下代码复制到 project 标签以内即可

<properties>
    <maven.compiler.source>10.0.1</maven.compiler.source>
    <maven.compiler.target>10.0.1</maven.compiler.target>
    <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
    <jersey.version>2.27</jersey.version>
</properties>

保存文件之后，会弹出以下提示界面，点击 Enable Auto-Import 即可将会为你自动下载依赖

在项目中引入依赖

点击右侧的 Maven Pjojects 检查依赖包是否全部下载完整，当然如果是第一次下载的话是需要些时间，耐心等待即可，如果长时间没有下载完整，则需手动点击 Reimport All Maven Pjojects 或者 Download Sourse and/or Documentation ，未完成下载表现为 pom.xml 中有红色字体出现，或者以下界面的依赖包会有红色的波浪线

按下快捷键 Ctrl++Alt+Shift+S 呼出项目配置，将 Maven 引入的 jar 包放到 lib 文件夹下

Hello Wolrd 测试

在 src/main/java 中创建包 com.API.actions 用来保存测试类文件

新建 Hello.java ，将以下代码复制进去即可

package com.API.actions;

import javax.ws.rs.GET;
import javax.ws.rs.Path;
import javax.ws.rs.Produces;
import javax.ws.rs.core.MediaType;

@Path("hello")

public class Hello {

    @GET
    @Produces(MediaType.TEXT_PLAIN)
    public String sayHello() {
        return "Hello,I am text!";
    }

}

配置 web.xml

<servlet>
    <servlet-name>JAX-RS Servlet</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.API.actions</param-value>
        <!-- 这里的配置包路经必须是与之间创立用于存储测试类的包路径一致 -->
    </init-param>

    <load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
    <servlet-name>JAX-RS Servlet</servlet-name>
    <url-pattern>/api/*</url-pattern>
</servlet-mapping>

点击启动 Tomcat 服务，稍等片刻

在浏览器中输入 http://127.0.0.1:8080/api/hello 即可看到结果

在 PostMan 里也可以获取结果
