springBoot常見問題報錯二

這個問題一般是項目啓動不起來,jar導致的原因

只需把衝突的jar提取出來  然後聲明一下版本

在pom.xml中使用<dependencyManagement> 這個標籤即可

案例:

    

<dependencyManagement>
    <dependencies>
        <dependency>
            <groupId>com.google.guava</groupId>
            <artifactId>guava</artifactId>
            <version>19.0</version>
        </dependency>
        <dependency>
            <groupId>com.google.protobuf</groupId>
            <artifactId>protobuf-java</artifactId>
            <version>3.0.0</version>
        </dependency>
    </dependencies>
</dependencyManagement>
