Question

我的项目名为car-rental，其中包含业务逻辑（使用maven构建）。我将这个项目用作其他项目中的依赖项，名为car-rental。它被声明为：

    <dependency>
        <groupId>com.car.rental</groupId>
        <artifactId>car-rental-model</artifactId>
        <version>1.0</version>
    </dependency>

在IDE Eclipse编译期间，汽车租赁会从依赖项中查看所有类。但是在部署到Java EE容器（例如GlassFish）之后，没有看到类。服务器中已部署的项目不包含依赖项类。

汽车租赁项目不包含任何特定的构建定义：

<build>
    <plugins>
        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-war-plugin</artifactId>
            <version>2.2</version>
            <configuration>
                <archive>
                    <manifest>
                        <addClasspath>true</addClasspath>
                    </manifest>
                </archive>
            </configuration>
        </plugin>
        <plugin>
            <artifactId>maven-assembly-plugin</artifactId>
            <version>2.2.2</version>
            <configuration>
                <descriptorRefs>
                    <descriptorRef>jar-with-dependencies</descriptorRef>
                </descriptorRefs>
            </configuration>
        </plugin>
    </plugins>
</build>

在maven打包之后，目标目录中的car-rental-1.0包含来自业务依赖的必需类。

这是我的租车项目结构：

可能我应该以某种方式将业务依赖关系链接到pom.xml文件中，但我不知道如何...或者我可能错了？

更新

汽车租赁模型打包为* .jar文件

<groupId>com.car.rental</groupId>
<artifactId>car-rental-model</artifactId>
<version>1.0</version>
<packaging>jar</packaging>
<name>car-rental-model</name>

汽车租赁打包为* .war文件

<modelVersion>4.0.0</modelVersion>
<groupId>com.car.rental</groupId>
<artifactId>car-rental</artifactId>
<version>1.0</version>
<packaging>war</packaging>

dispatcher-servlet.xml仅包含对其他配置文件的引用，这些配置文件仅存储Tiles，控制器或DAO实现的配置 - 放在这里并不重要......可能除了Hibernate映射：

<bean id="sessionFactory"
    class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean">
    <property name="dataSource" ref="dataSource" />
    <property name="hibernateProperties">
        <value>
            hibernate.dialect=org.hibernate.dialect.H2Dialect
            hibernate.hbm2ddl.auto=create
            hibernate.ejb.naming_strategy=org.hibernate.cfg.ImprovedNamingStrategy
            hibernate.connection.charSet=UTF-8
            hibernate.bytecode.provider=javassist
            hibernate.show_sql=true
            hibernate.format_sql=true
        </value>
    </property>
    <property name="annotatedClasses">

我认为您的配置可能如下所示

Car rental model

            </plugin>
        </plugins>
    </build>
</project>

我在所有项目中使用相同的配置，它工作正常。如果所有人都拥有maven-compiler-plugin，我宁愿创建一个包含公共部分的父级。
