依賴傳遞

只添加了一個struts2-core依賴，發現項目中出現了不少jar，這種狀況叫依賴傳遞java

查找座標

依賴版本衝突的解決

一、第一聲明優先原則mysql

<dependencies>
  <!--   spring-beans-4.2.4 -->
      <dependency>
          <groupId>org.springframework</groupId>
          <artifactId>spring-context</artifactId>
          <version>4.2.4.RELEASE</version>
      </dependency>
  
  
<!--   spring-beans-3.0.5 -->
      <dependency>
          <groupId>org.apache.struts</groupId>
          <artifactId>struts2-spring-plugin</artifactId>
          <version>2.3.24</version>
      </dependency>

二、路徑近者優先原則git

本身添加jar包(本身明確的添加Jar包)github

<dependency>
          <groupId>org.springframework</groupId>
          <artifactId>spring-beans</artifactId>
          <version>4.2.4.RELEASE</version>
      </dependency>

三、排除原則web

<dependency>
          <groupId>org.apache.struts</groupId>
          <artifactId>struts2-spring-plugin</artifactId>
          <version>2.3.24</version>
          <exclusions>
            <exclusion>
              <groupId>org.springframework</groupId>
              <artifactId>spring-beans</artifactId>
            </exclusion>
          </exclusions>
      </dependency>

四、版本鎖定原則spring

<properties>
        <spring.version>4.2.4.RELEASE</spring.version>
        <hibernate.version>5.0.7.Final</hibernate.version>
        <struts.version>2.3.24</struts.version>
    </properties>

    <!-- 鎖定版本，struts2-2.3.2四、spring4.2.四、hibernate5.0.7 -->
    <dependencyManagement>
        <dependencies>
            <dependency>
                <groupId>org.springframework</groupId>
                <artifactId>spring-context</artifactId>
                <version>${spring.version}</version>
            </dependency>
</dependencies>
</dependencyManagement>
