在 Apache Shiro 中初始化异常错误

Question

运行测试时出现以下错误。我不明白这一点，因为我是 shiro 的新手。请帮助我

这是 shiro.ini 文件。请告诉我我犯了什么错误

#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

它说它无法启动 java.sql.datasource..我应该怎么做才能启动它

您需要指定实例化的具体数据源，以防 MySQL 使用：

com.mysql.jdbc.jdbc2.optional.MysqlDataSource

或

com.mysql.jdbc.jdbc2.optional.MysqlConnectionPoolDataSource

另请参阅：https://dev.mysql.com/doc/connector-j/5.1/en/connector-j-reference-configuration-properties.html

而不是接口 javax.sql.DataSource - 无法构造，正如异常告诉你的那样：

原因：org.apache.shiro.config.ConfigurationException：无法 实例化类[javax.sql.DataSource]

您还需要在类路径中包含 MySQL 连接器 JAR 文件
