首先权威地址官方地址:https://freemarker.apache.org/
中文版使用手册地址:http://freemarker.foofun.cn/toc.html
1.日期格式及解决日期为NULL报错的写法
${(user.birthday?string("yyyy-MM-dd"))!} //--或者-- ${(user.birthday?string("yyyy-MM-dd"))!'--'} |
2.判断对象是否存在再进行操作
<#if user?? >「${user.name }」<#else>无</#if> |
3.循环及计数使用
<#list listUser as user> <#if user?? >「${user.name }」<#else>无</#if> <#if user?counter gt 3 > ${user.email} </#if> </#if> |

Spring Boot 的核心注解SpringBootApplication引起的探究
1.Spring Boot 的核心注解是哪个?
先上一个工程的启动配置项看下:
项目比较老混杂了spring boot,dubbo,jersey注册等
package com.pomelolee.cms; import com.ctrip.framework.apollo.spring.annotation.EnableApolloConfig; import com.pomelolee.boot.dubbo.annotation.EnableDubboProvider; import org.glassfish.jersey.server.ResourceConfig; import org.glassfish.jersey.servlet.ServletProperties; import org.springframework.beans.factory.config.BeanDefinition; import org.springframework.boot.SpringApplication; import org.springframework.boot.autoconfigure.SpringBootApplication; import org.springframework.boot.builder.SpringApplicationBuilder; import org.springframework.boot.web.support.SpringBootServletInitializer; import org.springframework.cloud.client.discovery.EnableDiscoveryClient; import org.springframework.cloud.netflix.feign.EnableFeignClients; import org.springframework.context.annotation.Bean; import org.springframework.context.annotation.ClassPathScanningCandidateComponentProvider; import org.springframework.context.annotation.ImportResource; import org.springframework.util.ClassUtils; import java.util.HashSet; import java.util.Set; @EnableFeignClients @SpringBootApplication @EnableApolloConfig @EnableDiscoveryClient @EnableDubboProvider @ImportResource("classpath*:/META-INF/spring/spring-job.xml") public class Application extends SpringBootServletInitializer { public static void main(String[] args) { SpringApplication.run(Application.class, args); } @Override protected SpringApplicationBuilder configure(SpringApplicationBuilder application) { return application.sources(Application.class); } @Bean public ResourceConfig resourceConfig() { ResourceConfig resourceConfig = new ResourceConfig(); ClassPathScanningCandidateComponentProvider scanner = new ClassPathScanningCandidateComponentProvider(true); Set<beandefinition> beanDefinitionSet = scanner.findCandidateComponents("com.pomelolee.cms.service"); beanDefinitionSet.addAll(scanner.findCandidateComponents("com.pomelolee.cms.facade")); beanDefinitionSet.addAll(scanner.findCandidateComponents("com.pomelolee.cms.config")); Set<Class<?>> clazzSet = new HashSet<Class<?>>(); for (BeanDefinition beanDefinition : beanDefinitionSet) { clazzSet.add( ClassUtils.resolveClassName( beanDefinition.getBeanClassName(), resourceConfig.getClassLoader())); } resourceConfig.registerClasses(clazzSet); resourceConfig.property(ServletProperties.FILTER_FORWARD_ON_404, true); return resourceConfig; } } </beandefinition> |
@SpringBootApplication 注解,就是 Spring Boot 的核心注解。
