```xml
org.noear
solon-view-beetl
```
#### 1、描述
视图扩展插件，为 Solon View 提供基于 beetl（[代码仓库](https://gitee.com/xiandafu/beetl)）的框架适配。
#### 2、应用示例
DemoController.java
```java
//顺便，加个国际化在模板里的演法
@I18n
@Controller
public class DemoController{
@Mapping("/test")
public ModelAndView test() {
ModelAndView model = new ModelAndView("beetl.htm");
model.put("title", "dock");
model.put("msg", "你好 world!");
return model;
}
}
```
resources/templates/beetl.htm
```html
${title}
beetl::${msg}；i18n::${@i18n.get("login.title")}
```
#### 3、支持扩展定制示例
```java
@Configuration
public class Config {
@Bean
public void configure(BeetlRender render){
render.putVariable("demo_var", "1");
render.putDirective("demo_tag", DemoTag.class);
render.getProvider(); //:GroupTemplate
render.getProviderOfDebug();
}
}
```
#### 4、自定义标签示例
以插件自带的权限验证标签为例：
```xml
<#authPermissions name="user:del">
我有user:del权限
```
自定义标签和共享对象代码实现（自定义标签，v2.8.1 后支持注入）：
```java
@Component("view:authPermissions")
public class AuthPermissionsTag extends Tag {
@Override
public void render() {
String nameStr = (String) getHtmlAttribute(AuthConstants.ATTR_name);
String logicalStr = (String) getHtmlAttribute(AuthConstants.ATTR_logical);
if (Utils.isEmpty(nameStr)) {
return;
}
String[] names = nameStr.split(",");
if (names.length == 0) {
return;
}
if (AuthUtil.verifyPermissions(names, Logical.of(logicalStr))) {
this.doBodyRender();
}
}
}
@Component("share:demo1")
public class Demo {
public String hello(){
return "hello";
}
}
```
