java – 在一个简单的Spring启动项目中包含许多第三方jar时会发

是否可以从我自己的一个JAR中使用API??,而不包括它的依赖？

我创建了一个独立的maven项目(A),它是一个API模块,它使用了许多第三方jar,应该在几个项目中使用.但是在一个Spring引导项目(B)中,由于A引入了它的依赖项,Spring引导项目不能很好地工作.

如果A被排除在pom之外,则弹簧启动效果很好.但我确实需要几个API.我该如何解决这个问题？

一开始,一切都运作良好.它是一个纯控制台应用程序.
Pom就像下面这样.

<dependencies>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter</artifactId>
    </dependency>
    <!-- 
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-web</artifactId>
    </dependency>
     -->
    <!-- 
    <dependency>
        <groupId>InsuranceWrapper</groupId>
        <artifactId>InsuranceWrapper</artifactId>
        <version>1.0</version>
    </dependency>
     --> 
    </dependencies>

然后我将InsuranceWrapper添加到它,它将有一个错误.

java.lang.IllegalStateException: Could not evaluate condition on org.springframework.boot.autoconfigure.jdbc.DataSourceTransactionManagerAutoConfiguration$TransactionManagementConfiguration due to org/springframework/web/servlet/view/freemarker/FreeMarkerConfigurer not found. Make sure your own configuration does not rely on that class. This can also happen if you are @ComponentScanning a springframework package (e.g. if you put a @ComponentScan in the default package by mistake)
    at org.springframework.boot.autoconfigure.condition.SpringBootCondition.matches(SpringBootCondition.java:55) ~[spring-boot-autoconfigure-1.3.1.RELEASE.jar:1.3.1.RELEASE]
    at

    at java.lang.ClassLoader.loadClass(ClassLoader.java:357) ~[na:1.8.0_45]
    ... 38 common frames omitted

然后我认为spring boot可能会认为我是一个web项目.所以我添加了spring boot web.现在发生另一个错误.

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'entityManagerFactory' defined in class path resource [org/springframework/boot/autoconfigure/orm/jpa/HibernateJpaAutoConfiguration.class]: Invocation of init method failed; nested exception is java.lang.NoSuchMethodError: javax.persistence.spi.PersistenceUnitInfo.getValidationMode()Ljavax/persistence/ValidationMode;
    at org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.initializeBean(AbstractAutowireCapableBeanFactory.java:1578) ~[spring-beans-4.2.4.RELEASE.jar:4.2.4.RELEASE]
    at 
Caused by: java.lang.NoSuchMethodError: javax.persistence.spi.PersistenceUnitInfo.getValidationMode()Ljavax/persistence/ValidationMode;
    at org.hibernate.jpa.boot.internal.PersistenceUnitInfoDescriptor.getValidationMode(PersistenceUnitInfoDescriptor.java:99) ~[hibernate-entitymanager-4.3.11.Final.jar:4.3.11.Final]

搜索了这些错误,没有任何线索.我的A项目是一个复杂的春天休眠项目.这就是为什么我问这个问题,只是想要一个干净的B环境,同时使用A的几个API.

UPDATE

添加spring-boot-starter-freemarker来修复第一个错误

UPDATE

更新mvn树

UPDATE

添加以下两个排除项,现在没有错误.

<exclusions>
    <exclusion>
        <artifactId>*</artifactId>
        <groupId>org.hibernate</groupId>
    </exclusion>
    <exclusion>
        <artifactId>*</artifactId>
        <groupId>org.slf4j</groupId>
    </exclusion>
</exclusions>

但是因为包含了春季网络..它将从后面启动一个tomcat,这非常烦人..

UPDATE

因为任何弹簧网都会使弹簧靴现在认为它是一个网络项目,最后所有的弹簧网都被移除了.并且spring-boot-starter-freemarker也被删除,因为它实际上没有被使用.

<exclusions>
        <exclusion>
            <artifactId>*</artifactId>
            <groupId>org.hibernate</groupId>
        </exclusion>
        <exclusion>
            <artifactId>*</artifactId>
            <groupId>org.slf4j</groupId>
        </exclusion>
        <exclusion>
            <artifactId>freemarker</artifactId>
            <groupId>org.freemarker</groupId>
        </exclusion>
        <exclusion>
            <artifactId>spring-web</artifactId>
            <groupId>org.springframework</groupId>
        </exclusion>
        <exclusion>
            <artifactId>struts2-spring-plugin</artifactId>
            <groupId>org.apache.struts</groupId>
        </exclusion>
    </exclusions>

现在一切都有效..

解决方法

要从jar / target目录中排除任何文件,您可以使用< excludes> pom.xml文件中的标记.

在下一个示例中,将不包含扩展名为.properties的所有文件：

<build>
    <resources>
        <resource>
            <directory>src/main/resources</directory>
            <excludes>
                <exclude>*.properties</exclude>
            </excludes>
            <filtering>false</filtering>
        </resource>
    </resources>
</build>

还看看这个

<dependencies>
    <dependency>
      <groupId>sample.ProjectB</groupId>
      <artifactId>Project-B</artifactId>
      <version>1.0-SNAPSHOT</version>
      <exclusions>
        <exclusion>
          <groupId>sample.ProjectE</groupId> <!-- Exclude Project-E from Project-B -->
          <artifactId>Project-E</artifactId>
        </exclusion>
      </exclusions>
    </dependency>
  </dependencies>
