好的,关于你的问题,我可以回答如下:
首先,你需要在Spring Security配置文件中配置数据库连接信息,具体步骤如下:
1. 导入Spring Security和JDBC相关的依赖。
```xml
<dependency>
<groupId>org.springframework.security</groupId>
<artifactId>spring-security-web</artifactId>
<version>5.3.3.RELEASE</version>
</dependency>
<dependency>
<groupId>org.springframework.security</groupId>
<artifactId>spring-security-config</artifactId>
<version>5.3.3.RELEASE</version>
</dependency>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-jdbc</artifactId>
<version>5.2.8.RELEASE</version>
</dependency>
<dependency>
<groupId>mysql</groupId>
<artifactId>mysql-connector-java</artifactId>
<version>8.0.21</version>
</dependency>
```
2. 在Spring配置文件中配置数据库连接信息。
```xml
<bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource">
<property name="driverClassName" value="com.mysql.cj.jdbc.Driver"/>
<property name="url" value="jdbc:mysql://localhost:3306/test?useSSL=false"/>
<property name="username" value="root"/>
<property name="password" value="123456"/>
</bean>
<!-- 配置Spring Security -->
<security:http auto-config="true">
<security:intercept-url pattern="/admin/**" access="ROLE_ADMIN"/>
<security:form-login login-page="/login" default-target-url="/welcome" authentication-failure-url="/login?error"/>
<security:logout logout-success-url="/login?logout"/>
</security:http>
<security:authentication-manager>
<security:authentication-provider>
<security:jdbc-user-service data-source-ref="dataSource"
users-by-username-query="select username,password,enabled from users where username=?"
authorities-by-username-query="select username,authority from authorities where username=?"/>
</security:authentication-provider>
</security:authentication-manager>
```
其中,`users-by-username-query`和`authorities-by-username-query`分别用于查询用户信息和用户权限信息。这里的查询语句需要根据实际情况进行修改。
接下来,你需要实现用户固定授权。可以通过在数据库中添加一个`authorities`表来实现。表结构如下:
```sql
CREATE TABLE authorities (
username VARCHAR(50) NOT NULL,
authority VARCHAR(50) NOT NULL,
PRIMARY KEY (username,authority),
CONSTRAINT fk_authorities_users FOREIGN KEY(username) REFERENCES users(username)
);
```
然后,在`authorities`表中添加用户的角色信息。例如,如果用户`admin`具有`ROLE_ADMIN`角色,则可以添加如下记录:
```sql
INSERT INTO authorities(username,authority) VALUES('admin','ROLE_ADMIN');
```
这样,当用户`admin`登录时,就会被授予`ROLE_ADMIN`角色。
以上就是实现Spring Security连接数据库并实现用户固定授权的基本步骤。希望我的回答能够帮助到你!
