使用maven-war-plugin和spring BOM

Question

我試圖將Spring BOM添加到我的項目中。我的POM在下面。

1. 我在這裏沒有做正確的事情嗎？

2. 此外，一個半相關的問題：爲什麼spring-ws，spring-data-jpa和其他版本號與spring core，context等版本不一致？

   <build> 
       <finalName>myproject</finalName> 
       <plugins> 
        <plugin> 
         <version>3.1</version> 
         <artifactId>maven-compiler-plugin</artifactId> 
         <configuration> 
          <source>1.7</source> 
          <target>1.7</target> 
         </configuration> 
        </plugin> 
       </plugins> 
   </build> 
   
   <dependencyManagement> 
       <dependencies> 
        <dependency> 
         <groupId>org.springframework</groupId> 
         <artifactId>spring-framework-bom</artifactId> 
         <version>4.0.3.RELEASE</version> 
         <type>pom</type> 
         <scope>import</scope> 
        </dependency> 
        <dependency> 
         <groupId>org.springframework</groupId> 
         <artifactId>spring-core</artifactId> 
         <exclusions> 
          <exclusion> 
           <groupId>commons-logging</groupId> 
           <artifactId>commons-logging</artifactId> 
          </exclusion> 
         </exclusions> 
        </dependency> 
        <dependency> 
         <groupId>org.springframework</groupId> 
         <artifactId>spring-context</artifactId> 
        </dependency> 
       ... 
       </dependencies> 
   </dependencyManagement> 
   
   <dependencies> 
   
       <!-- Spring --> 
       <dependency> 
        <groupId>org.springframework.ws</groupId> 
        <artifactId>spring-ws-core</artifactId> 
        <version>${spring-ws.version}</version> 
       </dependency> 
       <dependency> 
        <groupId>org.springframework.data</groupId> 
        <artifactId>spring-data-jpa</artifactId> 
        <version>${spring-data-jpa.version}</version> 
       </dependency> 
   ... 
   </dependencies> 
   

它產生以下錯誤：

Answer 1

非BOM Spring的依賴走在dependencies部分，不dependencyManagement。

<dependencies> 

    <!-- Spring --> 
    <dependency> 
     <groupId>org.springframework.ws</groupId> 
     <artifactId>spring-ws-core</artifactId> 
     <version>${spring-ws.version}</version> 
    </dependency> 
    <dependency> 
     <groupId>org.springframework.data</groupId> 
     <artifactId>spring-data-jpa</artifactId> 
     <version>${spring-data-jpa.version}</version> 
    </dependency> 
    <dependency> 
     <groupId>org.springframework</groupId> 
     <artifactId>spring-core</artifactId> 
     <exclusions> 
      <exclusion> 
       <groupId>commons-logging</groupId> 
       <artifactId>commons-logging</artifactId> 
      </exclusion> 
     </exclusions> 
    </dependency> 
    <dependency> 
     <groupId>org.springframework</groupId> 
     <artifactId>spring-context</artifactId> 
    </dependency> 
</dependencies>
