有什么提示嗎？

Answer 1

我建議使用Spring和Spring Security提供的物料清單poms以及版本屬性，這將簡化依賴管理和版本沖突。

1. 在Spring和Spring Security版本中添加屬性
2. 包括用於SPring安全性和SPring的物料清單
3. 清理依賴

添加屬性

在您的pom.xml添加以下內容（為了方便訪問，我通常將它們放在頂部）。

<properties>
    <spring.version>4.0.5.RELEASE</spring.version>
    <spring-security.version>3.2.4.RELEASE</spring-security.version>
</properties>

包括物料清單

添加dependencyManagement部分以導入2個bom項目

<dependencyManagement>
    <dependency>
        <groupId>org.springframework.security</groupId>
        <artifactId>spring-security-bom</artifactId>
        <version>${spring-security.version}</version>
        <type>pom</type>
        <scope>import</scope>
    </dependency>
    <dependency>
        <groupId>org.springframework</groupId>
        <artifactId>spring-framework-bom</artifactId>
        <version>${spring.version}</version>
        <type>pom</type>
        <scope>import</scope>
    </dependency>
</dependencyManagement>

請注意對前面提供的版本屬性的引用。 現在，如果您想更新Spring，則只需更改1件事，那就是spring.version屬性。

清理依賴

由於使用了bom以及我們導入了它們的事實，因此您可以清理依賴項部分。 只需刪除所有版本元素，而不是直接需要的依賴項（這些將被傳遞）。

<dependencies>
    <dependency>
        <groupId>org.springframework.security</groupId>
        <artifactId>spring-security-web</artifactId>
    </dependency>
    <dependency>
        <groupId>org.springframework.security</groupId>
        <artifactId>spring-security-config</artifactId>
    </dependency>
    <dependency>
        <groupId>org.springframework.security</groupId>
        <artifactId>spring-security-ldap</artifactId>
    </dependency>
    <dependency>
        <groupId>org.springframework</groupId>
        <artifactId>spring-webmvc</artifactId>
    </dependency>
    <dependency>
        <groupId>org.springframework</groupId>
        <artifactId>spring-orm</artifactId>
    </dependency>
// Non Spring Dependencies ommitted
</dependencies>

這些是您唯一需要的Spring Dependency。

最后的幾點注意事項

1. 不建議使用commons-logging，而是使用slf4j參見參考指南
2. 在xml配置文件spring-beans.xsd而不是spring-beans-4.0.xsd使用無版本xsd。 這將確保您始終將xsd的最兼容版本用於您的spring版本。
