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
