Apache Shiro JDBC連接問題

Question

我正在嘗試連接到數據庫以啓動基準用戶身份驗證程序。我能夠使用shiro.ini來獲取用戶角色，但是在嘗試使用JDBC連接運行程序時出現錯誤。我曾嘗試同時使用Microsoft sqljdbc42.jar和jTDS jar文件，結果沒有任何區別。無論哪種方式，我得到以下錯誤：

[ERROR] No plugin found for prefix 'java' in the current project and in the plugin groups [org.apache.maven.plugins, org.codehaus.mojo] available from the repositories [local (C:\Users\mainuser.m2\repository), central (https://repo.maven.apache.org/maven2)] -> [Help 1]

我見過一對夫婦爲「找到的前綴無插件」，但沒有爲「Java」作爲不同的故障排除問題，所以我在一個頭緒繼續。

這裏是我的Shiro.ini文件，使用JTDS罐子：

[main] 
ds = net.sourceforge.jtds.jdbcx.JtdsDataSource 
ds.serverName = SQL5 
ds.user = myUser 
ds.password = myPassword 
ds.databaseName = myDatabase 

jdbcRealm = org.apache.shiro.realm.jdbc.JdbcRealm 
jdbcRealm.dataSource = $ds 
jdbcRealm.permissionsLookupEnabled = true 
jdbcRealm.authenticationQuery = "SELECT pswd FROM Users  WHERE user = ?" 
jdbcRealm.userRolesQuery = "SELECT role FROM Role WHERE user = jdbcRealm.permissionsQuery = "SELECT perm FROM Person WHERE user = ?" 

這裏是我的pom.xml文件，使用JTDS罐子：

Answer 1

前綴對於exec-maven-plugin是exec，因此您可以使用：mvn exec:java。但請注意，您還必須設置mainClass以允許此操作。
