<h3><a class="anchor" aria-hidden="true"></a>REST插件介绍</h3>
|
||
<p>
|
||
<a href="https://github.com/redkale/redkale-plugins/tree/master/src/org/redkalex/rest" target="_blank">org.redkalex.rest</a> 是基于HTTP服务的REST插件，提供了很简单的REST服务接口方便开发。REST根据加载的Service组件自动生成对应的HttpServlet。其接口比Spring Boot之类的REST服务框架要简化得多，不需要进行注解配置也可以按REST服务加载。
|
||
</p>
|
||
|
||
<h3><a class="anchor" aria-hidden="true"></a>快速上手</h3>
|
||
<p>
|
||
为了让REST生效，必须配置 <a href="redkale.html#redkale_confxml" target="_blank">application.xml</a> 中 HTTP 的 <server> 节点的nodeInterceptor属性值为 <b>org.redkalex.rest.RestNodeInterceptor</b> 。<br>
|
||
同时必须在<server> 节点 里增加 <rest> 子节点。配置介绍如下：<br>
|
||
</p>
|
||
<div class="highlight"><pre><span class="nt"><application</span> <span class="na">port=</span><span class="s">"5001"</span><span class="nt">></span>

|
||
<span class="c"><!-- </span>
|
||
<span class="c"> nodeInterceptor: 值必须要是 <b>org.redkalex.rest.RestNodeInterceptor</b>，且只能配置在protocol="HTTP"的server节点上，REST服务才会生效。</span>

<span class="c"><!-- </span>

<p>

通常配置都需要编写一个 <b>org.redkalex.rest.RestHttpServlet</b> 子类，主要用于获取当前用户信息和鉴权，且必须指定具体的User对象类。开发者的实现类可以参考 <a href="https://github.com/redkale/redkale-demo/tree/master/src/org/redkale/demo/base" target="_blank">redkale-demo</a> 中的BaseServlet类，以下是一个简单的范例: <br>

<p>
|
||
REST的设置方式有两大种: 一种是采用默认REST注解，一种是显式的设置。 <br>
|
||
第一种方式需要开发者对Service中的方法命名需要遵循一定规则, 如下范例，模块为Hello，Service类命名为HelloService，增删改查的方法采用createHello、deleteHello、updateHello、queryHello或其他xxxHello命名。REST插件加载任何没有标记@RestController、@RestMapping、@RestParam 的Service将按照一定规则生成默认值：<br>
|
||
1、@RestController.value() 默认值为Service类名的小写化并去掉service及后面字样, 视为模块名 <br>
|
||
2、@RestMapping.name() 默认值为Service的方法名小写化并去掉模块名字样 <br>
|
||
3、@RestParam.value() 如果方法名以find、delete开头且方法的参数只有一个且参数类型是基本数据类型或String，则默认值为"#"；若使用Java 8中带上 -parameters 编译项的新特性，默认值为参数名, 若没使用新特性则采用bean、bean2、bean3...的命名规则。<br>
