当出现上面错误的时候首先看一下pom.xml中有没有配置tomcat的相关插件
<build> <plugins> <plugin> <groupId>org.apache.tomcat.maven</groupId> <artifactId>tomcat7-maven-plugin</artifactId> <version>2.2</version> <configuration> <port>8080</port> <path>/</path> </configuration> </plugin> </plugins> </build>
如果已经配置,在查看是否存在父子工程依赖关系,如果存在,tomcat的插件声明一般在父类声明,要现在父工程中 maven-install(安装)
在子类项目中编译 maven-compile
TNSLSNR.EXE占用端口
错误报告:java.net.BindException: Address already in use: JVM_Bind <null>:8080
......
Caused by: java.net.BindException: Address already in use: JVM_Bind
错误解决:window+R键进入运行,输入cmd ,依次粘贴运行下面代码
CMD> sqlplus system/123456
SQL> call dbms_xdb.cfg_update(updateXML(dbms_xdb.cfg_get(), '/xdbconfig/sysconfig/protocolconfig/httpconfig/http-port/text()',8081));
/
-- 把FTP端口从2100改到2111
SQL> call dbms_xdb.cfg_update(updateXML(dbms_xdb.cfg_get(), '/xdbconfig/sysconfig/protocolconfig/ftpconfig/ftp-port/text()',2111));
/
SQL> commit;
SQL> exec dbms_xdb.cfg_refresh;
-- 检查修改是否已经成功
SQL> select dbms_xdb.cfg_get from dual;
这样,TNSLSNR.exe就会使用8081端口了
