春季启动标签



我使用的是Spring引导。

我有一个带有以下标签库的JSP页面:

<%@ taglib prefix="form" uri="http://www.springframework.org/tags/form"%>  
<%@ taglib prefix="sec" uri="http://www.springframework.org/security/tags"%>

当加载我的jsp页面时,我得到以下错误:

The absolute uri: http://www.springframework.org/security/tags cannot be resolved in either web.xml or the jar files deployed with this application

以下是我的POM依赖项:

<dependencies>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-security</artifactId>
    </dependency>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-data-jpa</artifactId>
    </dependency>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-web</artifactId>
    </dependency>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-test</artifactId>
        <scope>test</scope>
    </dependency>
    <dependency>
        <groupId>mysql</groupId>
        <artifactId>mysql-connector-java</artifactId>
    </dependency>
    <dependency>
        <groupId>javax.servlet</groupId>
        <artifactId>jstl</artifactId>
    </dependency>
    <dependency>
        <groupId>org.apache.tomcat.embed</groupId>
        <artifactId>tomcat-embed-jasper</artifactId>
        <scope>provided</scope>
    </dependency>
</dependencies>

有什么建议吗?

我添加了以下依赖项:

<dependency>
    <groupId>org.springframework.security</groupId>
    <artifactId>spring-security-taglibs</artifactId>
</dependency>

现在它起作用了。

添加以下依赖项

For : <%@ taglib prefix="form" uri="http://www.springframework.org/tags/form"%> :  
<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-web</artifactId>
</dependency>

For : <%@ taglib prefix="sec" uri="http://www.springframework.org/security/tags"%> :
<dependency>
    <groupId>org.springframework.security</groupId>
    <artifactId>spring-security-taglibs</artifactId>
</dependency>

使用Tomcat插件分级用户

如果您收到此错误,即使您在gradle.build 中声明了依赖项

runtime "org.springframework.security:spring-security-taglibs:${springSecurityVersion}"

您正在使用Tomcat插件:

apply plugin: 'com.bmuschko.tomcat'

然后,您必须运行渐变任务tomcatRunWar而不是tomcatRun,以便将库包含在servlet容器中。

添加taglib库以及安全性可以帮助我解决这个问题:

编译"org.springframework.boot:spring-boot启动器安全性:1.5.22.RELEASE"

implementation group: 'org.springframework.security', name: 'spring-security-taglibs', version: '4.2.11.RELEASE'
