我正在开发一个简单的JSF 2应用程序,而我遇到了托管bean的问题。我收到的错误是说找不到bean,当我查看战争时它没有任何已编译的bean。在我的pom.xml中,我有以下内容:
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

</configuration>
</plugin>
</plugins>
</build>
如果从warSourceDirectory中删除WebContent文件夹,我会在war文件中获取我的项目的其余部分,但这似乎不正确。该文件是由eclipse生成的,所以我认为它没关系。在WEB-INF中有一个类文件夹,它是空的。
我的项目文件夹结构是:
test
- src/
- sample/
- sampleBean.java
- WebContent/
- sample.xhtml
- WEB-INF/
- faces-config.xml
- web.xml
- META-IF/
但是我编译的war文件的结构是这样的:
test
- sample.xhtml
- WEB-INF/
- faces-config.xml
- web.xml
- classes/
- META-IF/
我的war文件中应该打包什么,编译后的bean应该在哪里?

您的问题是标准的Eclipse Web Tools不仅使用与Apache Maven用于Web应用程序的目录布局完全不同的目录布局,而且还使用不同的方式来指定库依赖关系。解决此问题的最简单方法是更改项目以使用Maven约定并重新导入项目:
1. Move all of your main (not unit test) java source files into directory `src/main/java`;
2. Move all of your unit test java source files into directory `src/test/java`;
3. Move all the files in WebContent into directory `src/main/webapp` (excluding class files and jar files);
4. Remove the following from your pom.xml:
a. `<outputDirectory>...</outputDirectory>`;
b. `<warSourceDirectory>${basedir}/WebContent</warSourceDirectory>`;
5. Delete the project from eclipse (but not the source files!);
6. Execute `mvn eclipse:clean` on your project from a command line;
7. Ensure that the .project file, .classpath file and content of .settings directory have been removed (manually if necessary);
8. Re-import the project into Eclipse as a 'Maven' project.
由于这是一个webapp,此时您可能会遇到编译错误,因为您的pom.xml文件似乎没有依赖项。至少,你需要:
<dependencies>
<dependency>
<groupId>javax.servlet</groupId>
<artifactId>javax.servlet-api</artifactId>
<version>3.0.1</version>
<scope>provided</scope>
</dependency>
</dependencies>
最后,您应该在pom.xml文件中指定maven-eclipse-plugin
的唯一情况是,您的Eclipse版本是否超过4年左右。此插件与现在内置到Eclipse中的Maven集成不兼容。使用的唯一安全目标是eclipse:clean
,用于删除旧的Eclipse项目配置。

你需要在maven开始时宣布这是一场战争:
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">
<modelVersion>4.0.0</modelVersion>
<groupId>com.my</groupId>
<artifactId>project</artifactId>
<name>MyProject</name>
<packaging>war</packaging>
<version>1.0.0-BUILD-SNAPSHOT</version>
然后在最后把maping的heping插件用于构建战争:
<plugins>
<plugin>
<artifactId>maven-eclipse-plugin</artifactId>
<version>2.9</version>
<configuration>
<additionalProjectnatures>
<projectnature>org.springframework.ide.eclipse.core.springnature</projectnature>
</additionalProjectnatures>
<additionalBuildcommands>
<buildcommand>org.springframework.ide.eclipse.core.springbuilder</buildcommand>
</additionalBuildcommands>
<downloadSources>true</downloadSources>
<downloadJavadocs>true</downloadJavadocs>
</configuration>
</plugin>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<version>2.5.1</version>
<configuration>
<source>1.7</source>
<target>1.7</target>
<compilerArgument>-Xlint:all</compilerArgument>
<showWarnings>true</showWarnings>
<showDeprecation>true</showDeprecation>
</configuration>
</plugin>
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>exec-maven-plugin</artifactId>
<version>1.2.1</version>
<configuration>
<mainClass>org.test.int1.Main</mainClass>
</configuration>
</plugin>
</plugins>
希望这有帮助
