Configure user logon in spring secruity database mode

This article will share with you an article about configuring user logon in spring secruity database mode. I hope this article will be helpful for you to learn about spring secruity.

A few days ago, I learned how to configure the user password directly in XML and use the spring security logon example. This method is suitable for demonstration. In most cases, real projects use databases or LDAP for user management. therefore, we will continue to learn how to use the database to configure user logon. Based on the previous example, the main changes are as follows:

Add database-related jar packages
All jar packages used are as follows, which may be redundant.

Program code

The Code is as follows:

Copy code

Antlr-2.7.7.jar Aopalliance. jar Commons-logging-1.1.jar Jstl-1.1.2.jar Mysql-connector-java-3.1.12-bin.jar Spring-aop-3.2.4.RELEASE.jar Spring-aspects-3.2.4.RELEASE.jar Spring-beans-3.2.4.RELEASE.jar Spring-context-3.2.4.RELEASE.jar Spring-context-support-3.2.4.RELEASE.jar Spring-core-3.2.4.RELEASE.jar Spring-e-xpression-3.2.4.RELEASE.jar Spring-jdbc-3.2.4.RELEASE.jar Spring-security-config-3.1.4.RELEASE.jar Spring-security-core-3.1.4.RELEASE.jar Spring-security-web-3.1.4.RELEASE.jar Spring-tx-3.2.4.RELEASE.jar Spring-web-3.2.4.RELEASE.jar Spring-webmvc-3.2.4.RELEASE.jar Standard-1.1.2.jar

Create a database and insert Test Data
The database script is as follows:

Program code

The Code is as follows:

Copy code

Create TABLE 'users '( 'User _ id' INT (10) unsigned not null, 'Username' VARCHAR (45) not null, 'Password' VARCHAR (45) not null, 'Enabled' tinyint (1) not null, Primary key ('user _ id ') ) ENGINE = InnoDB default charset = utf8; Create TABLE 'user _ roles '( 'User _ ROLE_ID 'INT (10) unsigned not null, 'User _ id' INT (10) unsigned not null, 'Authority 'VARCHAR (45) not null, Primary key ('user _ ROLE_ID '), KEY 'fk _ user_roles '('user _ id '), CONSTRAINT 'fk _ user_roles 'foreign key ('user _ id') REFERENCES 'users' ('user _ id ') ) ENGINE = InnoDB default charset = utf8; Insert INTO users (USER_ID, USERNAME, PASSWORD, ENABLED) VALUES (100, 'yihaomen', '123', TRUE ); Insert INTO user_roles (USER_ROLE_ID, USER_ID, AUTHORITY) VALUES (1,100, 'Role _ user ');

In this way, the users table and user_roles table are created in database security, and records are inserted.

Configure the database authentication method for spring securtiy

Program code

The Code is as follows:	Copy code
<Authentication-manager> <Authentication-provider> <Jdbc-user-service data-source-ref = "dataSource" Users-by-username-query =" Select username, password, enabled From users where USERNAME =? " Authorities-by-username-query =" Select u. username, ur. authority from users u, user_roles ur Where u. user_id = ur. user_id and u. username =? " /> </Authentication-provider> </Authentication-manager>

Start the program and run the following results,
