springboot servlet-api衝突 啟動失敗

最近的一個新專案用的springboot,踩了很多坑,記錄下;

異常資訊是網上搜的,自己的沒記,資訊如下:

原因是 我的 common pom.xml 已經引入了jar包,跟springboot自帶的jar包衝突

     pom.xml :

<dependency>
        <groupId>javax.servlet</groupId>
        <artifactId>servlet-api</artifactId>
        <version>${servlet.api.version}</version>
    </dependency>

解決方式就是在啟動類的pom.xml把引入common的servlet-api排除掉

pom.xml:

  <dependency>
        <groupId>com.test.haha</groupId>
        <artifactId>haha-connmanage-common</artifactId>
        <version>${project.version}</version>
        <exclusions>
            <exclusion>
                <artifactId>servlet-api</artifactId>
                <groupId>javax.servlet</groupId>
            </exclusion>
        </exclusions>
    </dependency>
