Spring Boot过滤器Filter 单个过滤器如果只是定义一个过滤器，直接通过@Configuration注解即可。package Cc.LiSen.Configurations; import org.slf4j.Logger; import org.slf4j.LoggerFactory; import org.springframework.context.annotation.Configuration; import javax.servlet.*; import javax.servlet.annotation.WebFilter; import java.io.IOException; /** * ClassName: CustomFilter <br/> * Description: <br/> * date: 2019/7/25 22:04<br/> * * @since JDK 1.8 */ @WebFilter(filterName = "CustomFilter", urlPatterns = "{/*}") public class CustomFilter implements Filter { private Logger logger = LoggerFactory.getLogger(this.getClass()); @Override public void init(FilterConfig filterConfig) throws ServletException { logger.info("初始化过滤器CustomFilter"); } @Override public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) throws IOException, ServletException { logger.info("过滤器CustomFilter开始工作，并转入下一个过滤"); chain.doFilter(request, response); logger.info("CustomFilter继续过滤"); } @Override public void destroy() { logger.info("过滤器CustomFilter销毁"); } }多个过滤器如果定义多个过滤器，需要通过FilterRegistrationBean提供setOrder方法，可以为filter设置排序值，让spring在注册web filter之前排序后再依次注册。启动类中利用@bean注册FilterRegistrationBean*温馨提示过滤器定义与上面类似，去掉@Configuration注解即可，这里不再赘述，然后修改启动类，增加以下代码package Cc.LiSen; import Cc.LiSen.Configurations.CustomFilter; import Cc.LiSen.Configurations.CustomFilterOther; import org.slf4j.Logger; import org.slf4j.LoggerFactory; import org.springframework.boot.SpringApplication; import org.springframework.boot.autoconfigure.SpringBootApplication; import org.springframework.boot.autoconfigure.domain.EntityScan; import org.springframework.boot.web.servlet.FilterRegistrationBean; import org.springframework.context.annotation.Bean; import org.springframework.context.annotation.ComponentScan; import org.springframework.data.jpa.repository.config.EnableJpaRepositories; @SpringBootApplication //SpringBoot 默认从App类往下面的包扫描 //所以如果控制器、实体等类与App不在一个包，同时不在下面的包时，必须手动指定包 @EnableJpaRepositories(basePackages = {"Cc.LiSen.Repositories", "Cc.LiSen.Services"}) public class App { private static final Logger logger = LoggerFactory.getLogger(App.class); public static void main(String[] args) { // System.setProperty("log.root","DEBUG,info,error"); // // System.setProperty("log.base","D:\\log4j\\base"); SpringApplication.run(App.class, args); } @Bean public FilterRegistrationBean filterRegistrationBean() { FilterRegistrationBean filterRegistrationBean = new FilterRegistrationBean(); filterRegistrationBean.setFilter(new CustomFilter()); filterRegistrationBean.setOrder(10); return filterRegistrationBean; } @Bean public FilterRegistrationBean filterRegistrationBeanOther() { FilterRegistrationBean filterRegistrationBean = new FilterRegistrationBean(); filterRegistrationBean.setFilter(new CustomFilterOther()); filterRegistrationBean.setOrder(20); return filterRegistrationBean; } } -

Spring Boot使用FastJson 什么是FastJson？FastJson是阿里巴巴旗下的一个开源项目之一，顾名思义它专门用来做快速操作json的序列化与反序列化的组件。它是目前json解析最快的开源组件没有之一！在这之前JackJson是最为出名的快速操作json的工具，当然，现在也很出名。阿里巴巴的FastJson虽然速度快，但是bug也是相当多，如果是在大型系统中并且对系统安全性要求比较高，仍然建议使用Jackjson。maven依赖 <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> <exclusions> <exclusion> <groupId>com.fasterxml.jackson.core</groupId> <artifactId>jackson-databind</artifactId> </exclusion> </exclusions> </dependency> <dependency> <groupId>com.alibaba</groupId> <artifactId>fastjson</artifactId> <version>1.2.75</version> </dependency>{message type="warning" content="fastjson虽然是阿里巴巴出品的，但是最近爆出很多bug，所以大项目上还是慎重使用"/}创建配置信息类我们接下来创建一个FastJsonConfiguration配置信息类，添加@Configuration注解让SpringBoot自动加载类内的配置，有一点要注意我们继承了WebMvcConfigurerAdapter这个类，这个类是SpringBoot内部提供专门处理用户自行添加的配置，里面不仅仅包含了修改视图的过滤还有其他很多的方法，比如拦截器，过滤器，Cors配置等。方式一：fastJson视图过滤配置package cn.notemi.configuration; import com.alibaba.fastjson.serializer.SerializerFeature; import com.alibaba.fastjson.support.config.FastJsonConfig; import com.alibaba.fastjson.support.spring.FastJsonHttpMessageConverter; import org.springframework.context.annotation.Configuration; import org.springframework.http.converter.HttpMessageConverter; import org.springframework.web.servlet.config.annotation.WebMvcConfigurerAdapter; import java.util.List; /** * Title：FastJsonConfiguration * Description：FastJson配置信息 * * @create 2017-08-08 下午 4:33 **/ @Configuration public class FastJsonConfiguration extends WebMvcConfigurerAdapter { /** * 修改自定义消息转换器 * @param converters 消息转换器列表 */ @Override public void configureMessageConverters(List<HttpMessageConverter<?>> converters) { //调用父类的配置 super.configureMessageConverters(converters); //创建fastJson消息转换器 FastJsonHttpMessageConverter fastConverter = new FastJsonHttpMessageConverter(); //创建配置类 FastJsonConfig fastJsonConfig = new FastJsonConfig(); //修改配置返回内容的过滤 fastJsonConfig.setSerializerFeatures( SerializerFeature.DisableCircularReferenceDetect, SerializerFeature.WriteMapNullValue, SerializerFeature.WriteNullStringAsEmpty ); fastConverter.setFastJsonConfig(fastJsonConfig); //将fastjson添加到视图消息转换器列表内 converters.add(fastConverter); } }方式二：自定义FastJsonHttpMessageConverter@Configuration public class FastJsonConfig { @Bean public FastJsonHttpMessageConverter fastJsonHttpMessageConverter() { FastJsonHttpMessageConverter fastJsonHttpMessageConverter = new FastJsonHttpMessageConverter(); com.alibaba.fastjson.support.config.FastJsonConfig fastJsonConfig = new com.alibaba.fastjson.support.config.FastJsonConfig(); fastJsonConfig.setDateFormat("yyyy-MM-dd"); fastJsonConfig.setCharset(StandardCharsets.UTF_8); fastJsonConfig.setSerializerFeatures( // SerializerFeature.WriteClassName, SerializerFeature.WriteMapNullValue, SerializerFeature.PrettyFormat, SerializerFeature.WriteNullListAsEmpty, SerializerFeature.WriteNullStringAsEmpty ); fastJsonHttpMessageConverter.setFastJsonConfig(fastJsonConfig); // 解决中文乱码 List<MediaType> fastMediaTypes = new ArrayList<>(); fastMediaTypes.add(MediaType.APPLICATION_JSON); fastJsonHttpMessageConverter.setSupportedMediaTypes(fastMediaTypes); return fastJsonHttpMessageConverter; } }FastJson配置实体调用setSerializerFeatures方法可以配置多个过滤方式，下面我们来介绍下常用的SerializerFeatures配置。FastJson SerializerFeaturesWriteNullListAsEmpty ：List字段如果为null,输出为[],而非nullWriteNullStringAsEmpty ： 字符类型字段如果为null,输出为"",而非nullDisableCircularReferenceDetect ：消除对同一对象循环引用的问题，默认为false（如果不配置有可能会进入死循环）WriteNullBooleanAsFalse：Boolean字段如果为null,输出为false,而非nullWriteMapNullValue：是否输出值为null的字段,默认为false。项目运行我们使用了过滤，SerializerFeature.WriteNullStringAsEmpty，本该显示null，显示为""，所以成功使用。

IntellIJ IDEA配置Maven以及修改默认Repository 修改Maven仓库路径在D盘(个人根据自身情况而定)新建文件配置D:\server\maven\中setting.xml文件，内容如下：<?xml version="1.0" encoding="UTF-8"?> <settings xmlns="http://maven.apache.org/SETTINGS/1.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/SETTINGS/1.0.0 http://maven.apache.org/xsd/settings-1.0.0.xsd"> <pluginGroups /> <proxies /> <servers /> <localRepository>D:/server/maven/repository</localRepository> <mirrors> <mirror> <id>alimaven</id> <mirrorOf>central</mirrorOf> <name>aliyun maven</name> <url>http://maven.aliyun.com/nexus/content/repositories/central/</url> </mirror> <mirror> <id>alimaven</id> <name>aliyun maven</name> <url>http://maven.aliyun.com/nexus/content/groups/public/</url> <mirrorOf>central</mirrorOf> </mirror> <mirror> <id>central</id> <name>Maven Repository Switchboard</name> <url>http://repo1.maven.org/maven2/</url> <mirrorOf>central</mirrorOf> </mirror> <mirror> <id>repo2</id> <mirrorOf>central</mirrorOf> <name>Human Readable Name for this Mirror.</name> <url>http://repo2.maven.org/maven2/</url> </mirror> <mirror> <id>ibiblio</id> <mirrorOf>central</mirrorOf> <name>Human Readable Name for this Mirror.</name> <url>http://mirrors.ibiblio.org/pub/mirrors/maven2/</url> </mirror> <mirror> <id>jboss-public-repository-group</id> <mirrorOf>central</mirrorOf> <name>JBoss Public Repository Group</name> <url>http://repository.jboss.org/nexus/content/groups/public</url> </mirror> <mirror> <id>google-maven-central</id> <name>Google Maven Central</name> <url>https://maven-central.storage.googleapis.com </url> <mirrorOf>central</mirrorOf> </mirror> <!-- 中央仓库在中国的镜像 --> <mirror> <id>maven.net.cn</id> <name>oneof the central mirrors in china</name> <url>http://maven.net.cn/content/groups/public/</url> <mirrorOf>central</mirrorOf> </mirror> </mirrors> </settings> IntellIJ IDEA 中配置MavenIdea 自带了apache maven，默认使用的是内置maven，所以我们可以配置全局setting，来调整一下配置，比如远程仓库地址，本地编译环境变量等。打开Settings,在输入框输入maven，如果本地设置了MAVEN_OPTS 系统环境变量，这个步骤可以忽略。如果配置了本地apache-maven setting.xml 中的软件源，这步骤可以忽略。
