NoClassDefFoundError在Spring boot中运行JSF

Question

我正在尝试使用primface来获得工作Spring-boot。我https://github.com/Zergleb/Spring-Boot-JSF-Example遵循了这个示例。我尝试将其从gradle移动到maven，因为项目的其他部分使用maven，但我总是得到

java.lang.NoClassDefFoundError: javax/servlet/jsp/JspFactory

我在搜索，找到了这个解决方案。lang.ClassNotFoundException:javax。servlet。jsp。jstl。果心但这对我不起作用。

这是我从pom文件的依赖列表：

我还尝试下载所需的库并将它们放入WEB-INF/lib，但没有成功。我用的是Intelij 14。

Answer 1

我遇到了这个问题，并将提供的作用域（不向tomcat发送jar文件）更改为在POM中编译作用域（将spring-boot-starter-tomcat.jar添加到WEB-INF\lib）。xml。更改后，tomcat可以毫无例外地启动我的应用程序。我希望，它能帮助其他人解决此类异常。

Answer 2

我能够使用mvn springboot： run在命令行运行它。在Intellij Idea中，我们可以将其作为Maven项目运行，并在命令行参数字段中给出“spring-boot： run”。对于Tomcat 7、Spring Boot 1.2.3、JSF Mojarra 2.2.11、PrimeFaces 6.1运行非常好。需要将以下内容添加到pom.xml.

<dependency>
        <groupId>javax.servlet</groupId>
        <artifactId>servlet-api</artifactId>
        <version>2.3</version>
        <scope>provided</scope>
    </dependency>

    <!-- https://mvnrepository.com/artifact/javax.servlet/javax.servlet-api -->
    <!--<dependency>
        <groupId>javax.servlet</groupId>
        <artifactId>javax.servlet-api</artifactId>
        <version>3.1.0</version>
        <scope>provided</scope>
    </dependency>-->

    <dependency>
        <groupId>javax.servlet</groupId>
        <artifactId>jsp-api</artifactId>
        <version>2.0</version>
        <scope>provided</scope>
    </dependency>
    <dependency>
        <groupId>javax.servlet</groupId>
        <artifactId>jstl</artifactId>
        <version>1.2</version>
    </dependency>

Answer 3

这种依赖关系的组合帮助我启动Spring Boot并使用JSF运行。

这些库为嵌入式Tomcat提供了正确处理JSFServlet请求和EL表达式所需的类。

    <dependency>
        <groupId>javax.servlet.jsp</groupId>
        <artifactId>jsp-api</artifactId>
        <version>2.2</version>
    </dependency>
    <dependency>
        <groupId>com.sun.el</groupId>
        <artifactId>el-ri</artifactId>
        <version>1.0</version>
    </dependency>
    <dependency>
        <groupId>javax.servlet</groupId>
        <artifactId>jstl</artifactId>
        <version>1.2</version>
    </dependency>
