我在尝试部署Java应用程序时遇到问题.

Cannot invoke Tomcat manager: Connection reset by peer: socket write error

要么

Cannot invoke Tomcat manager: Software caused connection abort: socket write error

在pom.xml中我有这个:

<plugin>
    <groupId>org.apache.tomcat.maven</groupId>
    <artifactId>tomcat7-maven-plugin</artifactId>
    <version>2.2</version>
    <configuration>
        <url>http://localhost:8085/manager/html</url>
        <server>tomcat7</server>
        <path>/java_web</path>
        <username>admin</username>
        <password>admin</password>
    </configuration>
</plugin>

在tomcat-users.xml中我有这个:

 <tomcat-users>
     <role rolename="admin"/>
     <role rolename="manager-script"/>
     <role rolename="manager-gui"/>
     <role rolename="manager-jmx"/>
     <user username="admin" password="admin" roles="manager-gui,admin,manager-jmx,manager-script" />
 </tomcat-users>

同样在Maven/conf/settings.xml中我有:

<server>
    <id>tomcat7</id>
    <username>admin</username>
    <password>admin</password>
</server>

当我想去的时候

http://localhost:8085/manager/html/deploy?path=%2Fjava_web&update=true

并输入用户名和密码(admin admin)我有错误:

403 Access Denied
You are not authorized to view this page. …

当我想添加数据库时遇到一些麻烦.

    _dataBase = QSqlDatabase::addDatabase("QPSQL");

调用此方法后,我有一个错误:

QSqlDatabase: QPSQL driver not loaded
QSqlDatabase: available drivers: QSQLITE QMYSQL QMYSQL3 QODBC QODBC3 QPSQL QPSQL7

我包括PATH可变路径:

PostgreSQL\9.3\bin
PostgreSQL\9.3\lib
PostgreSQL\9.3\include

我也将文件夹复制sqldrivers到Debug文件夹.还试图将dll drom这个文件夹复制到Debug.也不起作用.
