使用maven-war-plugin和Spring BOM

Question

我正在嘗試將Spring BOM添加到我的項目中。 我的POM在下面。

1. 我在這里做得不對嗎？

2. 另外，一個半相關的問題：為什么spring-ws，spring-data-jpa和其他版本的版本號不符合spring core，context等版本？

    <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> 

它會產生以下錯誤：

Answer 1

非BOM Spring依賴項位於dependencies部分，而不是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>

        </exclusions>
