要在Spring Boot应用中对接CAS并使用数据库，你需要做以下几步：
- 添加依赖到
pom.xml：
<dependencies>
<!-- Spring Boot Web Starter -->
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>
<!-- Spring Boot Security Starter -->
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-security</artifactId>
</dependency>
<!-- Spring Boot Data JPA Starter -->
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-data-jpa</artifactId>
</dependency>
<!-- Database Driver (比如MySQL) -->
<dependency>
<groupId>mysql</groupId>
<artifactId>mysql-connector-java</artifactId>
<scope>runtime</scope>
</dependency>
<!-- CAS Client -->
<dependency>
<groupId>org.jasig.cas.client</groupId>
<artifactId>cas-client-support-springboot</artifactId>
<version>版本号</version>
</dependency>
</dependencies>- 配置
application.properties或application.yml以连接数据库和CAS服务器：
spring.datasource.url=jdbc:mysql://localhost:3306/数据库名?useSSL=false
spring.datasource.username=数据库用户名
spring.datasource.password=数据库密码
spring.datasource.driver-class-name=com.mysql.jdbc.Driver
# CAS server configuration
cas.server-url-prefix=https://yourcas.server.com/cas
cas.server-login-url=https://yourcas.server.com/cas/login
cas.client-host-url=http://localhost:8080
# CAS service configuration
cas.service=http://localhost:8080/login- 创建一个实体类来表示数据库中的用户信息：
@Entity
public class User {
@Id
private String username;
// 其他属性和方法
}- 创建一个继承自
UserDetailsService的服务类来加载用户信息：
@Service
public class CustomUserDetailsService implements UserDetailsService {
@Autowired
private UserRepository userRepository;
@Override
public UserDetails loadUserByUsername(String username) throws UsernameNotFoundException {
User user = userRepository.findByUsername(username);
if (user == null) {
throw new UsernameNotFoundException("User not found");
}
// 构建UserDetails对象，通常使用User类实现
return new org.springframework.security.core.userdetails.User(
user.getUsername(),
user.getPassword(),
user.getAuthorities()
);
}
}
