Question

我正在尝试使用primfaces进行Spring-boot工作。我遵循了这个考试https://github.com/Zergleb/Spring-Boot-JSF-Example。我尝试将它从gradle移动到maven因为项目使用maven的其他部分，但我总是得到

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

我正在搜索，我找到了这个解决方案java.lang.ClassNotFoundException: javax.servlet.jsp.jstl.core.Config，但它对我没用。

这是我从pom文件中的依赖项列表：

我也尝试下载所需的库并将它们放入WEB-INF / lib但是没有用。我正在使用Intelij 14.

Answer 1

我可以使用mvn springboot运行它：在命令行运行。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提供“spring-boot：run”。 对于Tomcat 7，Spring Boot 1.2.3，JSF Mojarra 2.2.11，PrimeFaces 6.1 运行完全正常。需要将以下内容添加到pom.xml中。

<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 2

这种依赖关系的组合帮助我开始使用JSF运行Spring Boot。

这些库为嵌入式Tomcat提供了处理JSF servlet正确请求EL表达式的必要类。

    <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>
