我是 Apache Shiro 的新手，想使用它的功能对我的 RESTful Web 应用程序进行用户登录身份验证。我有一个允许用户登录的网络表单。用户名和密码存储在 MySQL 数据库中。我有以下方法来使用 Jersey 处理用户登录身份验证：
@Path("/login")
public class UserAccount {
Realm realm = new JdbcRealm();
SecurityManager sm = new DefaultSecurityManager(realm);
@Path("success")
@POST
@Consumes(MediaType.APPLICATION_JSON)
@Produces(MediaType.APPLICATION_JSON)
public Response userAuth(@FormParam("username") String username,
@FormParam("password") String password) {
Response r = null;
UsernamePasswordToken token = new UsernamePasswordToken(username, password);
token.setRememberMe(true);
SecurityUtils.setSecurityManager(sm);
Subject currentUser = SecurityUtils.getSubject();
try {
currentUser.login(token); //This throws an error upon form submission
r = Response.ok().entity(token).build();
} catch (IncorrectCredentialsException ice) {
System.out.println("Incorrect username/password!");
}
return r;
}
}
当我提交表单时，该行currentUser.login(token);导致错误。我认为这是因为我没有连接到我的数据库进行用户名和密码身份验证。但是如何连接我的后端数据库以在 Shiro 中进行身份验证？我按照 Shiro 网站上的教程进行操作，但不知道如何使用数据库连接进行身份验证。我相信我的代码中缺少一些通过 JDBC 领域进行身份验证的部分。
我把 Shiro 配置文件shiro.ini放在了 WEB-INF 目录下，它的内容是：
[main]
jdbcRealm = org.apache.shiro.realm.jdbc.JdbcRealm
jdbcRealm.permissionsLookupEnabled = true
jdbcRealm.authenticationQuery = "SELECT password FROM users WHERE username = ?"
jdbcRealm.userRolesQuery = "SELECT authority FROM user_roles WHERE username = ?"
ds = com.mysql.jdbc.jdbc2.optional.MysqlDataSource
ds.serverName = localhost
ds.user = root
ds.password = 123456
ds.databaseName = customer
jdbcRealm.dataSource = $ds
[users]
[roles]
[urls]
/myapp/login/** = authcBasic
更新（添加错误消息）：我提交表单后得到的详细错误消息是：
