Spring Boot 添加jersey-mvc-freemarker依赖后内置tomcat启动不了解决方案

2024-08-23 21:35:06   220人阅读

我在我的Spring Boot 项目的pom.xml中添加了jersey-mvc-freemarker依赖后，内置tomcat启动不了。

报错信息如下：

原因是因为jersey-mvc-freemarker中引用了

<groupId>javax.servlet</groupId>
<artifactId>servlet-api</artifactId>

然而内置tomcat依赖中也有此包，虽然没有此依赖，由于自己引入了依赖，导致spring-boot的内置tomcat启动冲突报错。

解决方案，在jersey-mvc-freemarker排除servlet-api即可

<dependency>
    <groupId>org.glassfish.jersey.ext</groupId>
    <artifactId>jersey-mvc-freemarker</artifactId>
    <version>2.23.2</version>
    <exclusions>
        <exclusion>
            <groupId>javax.servlet</groupId>
            <artifactId>servlet-api</artifactId>
        </exclusion>
    </exclusions>
</dependency>
