spring security maven dependency

Unable to locate Spring NamespaceHandler for XML schema namespace [

spring secutity dependency:

        <!-- Spring Security -->
        <dependency>
            <groupId>org.springframework.security</groupId>
            <artifactId>spring-security-core</artifactId>
            <version>${springsecurity.version}</version>
        </dependency>

        <dependency>
            <groupId>org.springframework.security</groupId>
            <artifactId>spring-security-web</artifactId>
            <version>${springsecurity.version}</version>
        </dependency>

        <dependency>
            <groupId>org.springframework.security</groupId>
            <artifactId>spring-security-config</artifactId>
            <version>${springsecurity.version}</version>
        </dependency>

或者：

        <!-- spring security -->
        <dependency>
            <groupId>org.springframework.security</groupId>
            <artifactId>spring-security-web</artifactId>
            <version>${springsecurity.version}</version>
        </dependency>
        <dependency>
            <groupId>org.springframework.security</groupId>
            <artifactId>spring-security-config</artifactId>
            <version>${springsecurity.version}</version>
        </dependency>

包含spring-security-web会自动下载spring-security-core。

不可缺少spring-security-config，因为其包含xsd文件，缺少该artifactId会报Unable to locate Spring NamespaceHandler for XML schema namespace的错。
