и это shiro.ini файл .Please дайте мне знать, что ошибка я сделал

#myRealm = MyRealm 
#myRealm.credentialsMatcher = $myRealmCredentialsMatcher 


ps = org.apache.shiro.authc.credential.DefaultPasswordService 
pm = org.apache.shiro.authc.credential.PasswordMatcher 
pm.passwordService = $ps 

aa = org.apache.shiro.authc.credential.AllowAllCredentialsMatcher 
sm = org.apache.shiro.authc.credential.SimpleCredentialsMatcher 

#jof = org.apache.shiro.jndi.JndiObjectFactory 
#jof.resourceName = jdbc/UserDB 
#jof.requiredType = javax.sql.DataSource 
#jof.resourceRef = true 
#; Note factories are automatically invoked via getInstance(), 
#; see org.apache.shiro.authc.config.ReflectionBuilder::resolveReference 
#jdbcRealm.dataSource = $jof 

ds = javax.sql.DataSource 
ds.url = jdbc:mysql://192.168.1.111:3306/Test 
ds.user = dbuser 
ds.password = dbuser 

jdbcRealm = org.apache.shiro.realm.jdbc.JdbcRealm 
#realm.permissionsLookupEnabled = true 
jdbcRealm.credentialsMatcher = $pm 
jdbcRealm.dataSource = $ds 

securityManager.realms = $jdbcRealm 


jdbcRealm = org.apache.shiro.realm.jdbc.JdbcRealm 

#ds = javax.sql.DataSource 
#ds.url = jdbc:mysql://192.168.1.111:3306/Test 
#ds.user = dbuser 
#ds.password = dbuser 
#jdbcRealm.dataSource = $ds 

# Configure JDBC realm SQL queries. 
jdbcRealm.authenticationQuery = select pass from users where name = ?; 
sha256Matcher = org.apache.shiro.authc.credential.HashedCredentialsMatcher 
sha256Matcher.hashAlgorithmName=SHA-256 
# enable matcher in iniRealm (object responsible for authentication) 
iniRealm.credentialsMatcher = $sha256Matcher 

Это говорит его не может инициировать java.sql.datasource..what я должен сделать, чтобы начать что

Answer 1

Вы должны указать конкретный DataSource, который получает инстанцированный, в случае MySQL используется:

com.mysql.jdbc.jdbc2.optional.MysqlDataSource 

или

com.mysql.jdbc.jdbc2.optional.MysqlConnectionPoolDataSource 

Смотрите также: http://dev.mysql.com/doc/refman/5.1/de/connector-j-reference-configuration-properties.html

вместо интерфейса javax.sql.DataSource - который не может быть построена, как исключение говорит вам:

причиненное по: org.apache.shiro.config.ConfigurationException: не удалось выполнить экземпляр класса [javax.sql.DataSource]

Вы также должны иметь файл JAR MySQL Connector в вашем пути к классам
