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
