solon-view-freemarker
```
#### 1、描述
视图扩展插件，为 Solon View 提供基于 freemarker 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("freemarker.ftl");
model.put("title", "dock");
model.put("msg", "你好 world!");
return model;
}
}
```
resources/templates/freemarker.ftl
```html
${title}
ftl::${msg}；i18n::${i18n.get("login.title")}
```
#### 3、支持扩展定制示例
```java
@Configuration
public class Config {
@Bean
public void configure(FreemarkerRender render){
render.putVariable("demo_var", "1");
render.putDirective("demo_tag", new DemoTag());
render.getProvider(); //:Configuration
render.getProviderOfDebug();
}
}
```
#### 4、自定义标签示例
以插件自带的权限验证标签为例：
```html
<#authPermissions name="user:del">
我有user:del权限
```
自定义标签和共享变量代码实现：
```java
@Component("view:authPermissions")
public class AuthPermissionsTag implements TemplateDirectiveModel {
@Override
public void execute(Environment env, Map map, TemplateModel[] templateModels, TemplateDirectiveBody body) throws TemplateException, IOException {
NvMap mapExt = new NvMap(map);
String nameStr = mapExt.get(AuthConstants.ATTR_name);
String logicalStr = mapExt.get(AuthConstants.ATTR_logical);
if (Utils.isEmpty(nameStr)) {
return;
}
String[] names = nameStr.split(",");
if (names.length == 0) {
return;
}
if (AuthUtil.verifyPermissions(names, Logical.of(logicalStr))) {
body.render(env.getOut());
}
}
}
@Component("share:demo1")
public class Demo {
public String hello(){
return "hello";
}
}
```
