freemarker页面空值问题和自定义函数

@Component
public class FreeMarkerUtils{

private DateTimeFormatter DF_LONG = DateTimeFormat.forPattern("yyyyMMddHHmmss");

}

 

在

import com.jagregory.shiro.freemarker.ShiroTags;
import com.jsdc.zhly.common.utils.FreeMarkerUtils;
import freemarker.template.TemplateModelException;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.view.freemarker.FreeMarkerConfigurer;

import javax.annotation.PostConstruct;

@Configuration
public class FreeMarkerConfig {

    @Autowired
    protected FreeMarkerConfigurer freeMarkerConfigurer;

    @PostConstruct
    public void setSharedVariable() throws TemplateModelException {
        freeMarkerConfigurer.getConfiguration().setSharedVariable("utils", new FreeMarkerUtils());
//将freemarkerutils注入

    }
}

 

在页面就可以直接用了 

<div class="words">${utils.forPattern(date)}</div>  格式化日期

日期为空： ${(user.birthDate?string("yyyy-MM-dd"))!'无数据 '}
