Spring Boot下使用拦截器

Spring Boot对于原来在配置文件配置的内容，现在全部体现在一个类中，该类需要继承自WebMvcConfigurationSupport类，并使用@Configuration进行注解，表示该类为一个JavaConfig类，其充当配置文件的角色

一、定义工程

二、导入依赖

<?xml version="1.0" encoding="UTF-8"?>





<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"





         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">





    <modelVersion>4.0.0</modelVersion>





    <parent>





        <groupId>org.springframework.boot</groupId>





        <artifactId>spring-boot-starter-parent</artifactId>





        <version>2.1.5.RELEASE</version>





        <relativePath/> <!-- lookup parent from repository -->





    </parent>





 





    <groupId>com.abc</groupId>





    <artifactId>06-interceptor</artifactId>





    <version>0.0.1-SNAPSHOT</version>





 





    <properties>





        <java.version>1.8</java.version>





    </properties>





 





    <dependencies>





        <!--热部署依赖-->





        <dependency>





            <groupId>org.springframework.boot</groupId>





            <artifactId>spring-boot-devtools</artifactId>





        </dependency>





 





        <dependency>





            <groupId>org.springframework.boot</groupId>





            <artifactId>spring-boot-starter-web</artifactId>





        </dependency>





 





        <dependency>





            <groupId>org.springframework.boot</groupId>





            <artifactId>spring-boot-starter-test</artifactId>





            <scope>test</scope>





        </dependency>





    </dependencies>





 





    <build>





        <plugins>





            <plugin>





                <groupId>org.springframework.boot</groupId>





                <artifactId>spring-boot-maven-plugin</artifactId>





            </plugin>





        </plugins>





    </build>





 





</project>

三、定义拦截器

四、定义处理器

五、定义配置文件类

五、测试
