问题：

启动JasperServer失败：org.springframework.beans.factory.BeanCreationException

濮阳品
2023-03-14


我正在尝试第一次启动Jasperserver，正如您可能认为的那样，它的结果并不是很好。

我所做的:

  1. 安装Tomcat v7.0.32
  2. 安装Jasperreport v7.1.0

注意:

  • 在安装jasperreport server时，我选择使用外部源。我已将其链接到Tomcat。
  • 在jasperreport安装过程中，我还安装了PostgreSQL。
  • 安装tomcat时，我选择使用不同的端口8000->9000。
  • 我正在使用Windows 10

我正在做的事:

  • 凝视tomcat管理器（以管理员身份）。
  • 在浏览器中打开localhost:9000/manager/html

错误:

  • 如果尝试访问localhost:9000/jasperserver:

  • 所以我检查了日志文件，发现多个文件中存在错误:

结论：

我真的不知道该怎么办！我试着谷歌它，但所有的东西都是旧的，与我得到的错误无关。希望你能帮我！

不支持主版本。次版本52.0表示Java版本不匹配，切换到Java 8

看起来，即使您安装了Tomcat所指向的JRE1.7，您的系统也安装了实际运行的JRE1.8。此外，您还没有安装JDK。编制Java类是需要的。

请尝试以下操作：

>

  • 从http://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html下载JDK 1.8 for Windows。你得先接受许可协议。

    运行安装程序。除了安装路径外，不应该有很多选项供您配置。请记住此路径以备以后使用

    安装程序完成后，搜索“环境变量”。此时，查找path变量和classpath。如果它们不在那里，您可以通过添加一个新变量来创建它们。

    编辑path变量，添加“；path\in\step\2\bin\”。如果您不记得，通常是c:\programfiles\\jdk1.8.0_131\bin\。path变量给出了javac、Java等可执行文件的位置。

    创建java_home变量并将其设置为“path/to/jdk”。它应该类似于C:\Program Files\Java\jdk1.6.0_25

    创建jre_home变量并将其设置为“path/to/jre”。它应该类似于jre_home=c:\program files\Java\jdk1.6.0_32\jre

    创建catalina_home变量，并将其设置为已安装Tomcat4.1的目录的路径。它应该看起来C:\Program Files\Apache\Tomcat\bin\startup

    创建classpath变量并将其设置为“path\common\lib\servlet-api.jar”。它应该类似于c:\apache-tomcat-6.0.14\lib\servlet-api.jar。

    通过在cmd上回显它们来检查这些设置是否正确。只需在cmd中键入%path%、%JAVA_HOME%、%JRE_HOME%等。它们应该生成与前面步骤中设置的值相同的值。

    最后，通过键入javac并在cmd上单击enter来检查Java是否已正确安装。如果您得到了类似“usage：javac...”的输出，那么它已经正确安装了。

    运行你的项目。

    path是操作系统(Windows、Mac OS X、Linux)使用的环境变量，它将在其中查找要运行的本机可执行程序。java_home、jre_home不是Java自己使用的。Apache Tomcat希望将其中一个环境变量设置为JDK或JRE的安装目录。classpath被tomcat等第三方应用程序用于将classpath中设置的内容注入到您制作的每个Java应用程序中。catalina_home指向tomcat的安装，启动时可能需要安装。.

    可能是因为您没有设置变量而导致错误
