java 代码2. 使用Spring security实现用户认证和授权的项目： (1)数据准备，在第三章实验3的基础上添加表t_customer、t_authoytity、t_customer_authority,添加若干登录用户和角色的实验数据。 （2）SpringBoot自动创建spring web项目，选取Spring web依赖、Thymeleaf、Jpa、mysqldriver依赖。 （3）在pojo包中编写实体类Customer和Authority实体类，并按照jpa的映射方式进行注解。 （4）在repository包中创建CustomerRepository和AuthorityRepository接口，创建并装配findByUsername和findAuthoritiesByUsername方法。 (5)在service包中创建CustomerService类实现getCustomer()和getCustomerAuthority()方法，并结合RedisApi对用户和权限数据实施redis缓存；创建UserDetailServiceImpl类，实现加载用户详细信息UserDetails 的loadUserByUsername()方法。。 (6)在controller包中创建FilmController类实现@GetMapping("/detail/{type}/{path}")请求映射以及对应的方法。 （7）在pom文件中引入spring security和jpa、redis依赖

很抱歉，我无法提供具体的代码，因为这是一个比较复杂的项目，需要您根据具体的业务需求和数据结构进行编写。但是，以下是一些关于使用Spring Security实现用户认证和授权的项目的代码实现的参考：

1. 实体类：

@Entity
@Table(name = "t_customer")
public class Customer implements Serializable {

    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private Long id;

    @Column(nullable = false, unique = true)
    private String username;

    @Column(nullable = false)
    private String password;

    @ManyToMany(fetch = FetchType.EAGER)
    @JoinTable(name = "t_customer_authority", joinColumns = {@JoinColumn(name = "customer_id", referencedColumnName = "id")},
            inverseJoinColumns = {@JoinColumn(name = "authority_id", referencedColumnName = "id")})
    private Set<Authority> authorities;

    // getters and setters
}

@Entity
@Table(name = "t_authority")
public class Authority implements Serializable {

    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private Long id;

    @Column(nullable = false, unique = true)
    private String name;

    @ManyToMany(mappedBy = "authorities")
    private Set<Customer> customers;

    // getters and setters
}

2. Repository接口：

public interface CustomerRepository extends JpaRepository<Customer, Long> {

    Customer findByUsername(String username);
}

public interface AuthorityRepository extends JpaRepository<Authority, Long> {

    Set<Authority> findAuthoritiesByUsername(String username);
}

3. Service类：

@Service
public class CustomerService {

    @Autowired
    private CustomerRepository customerRepository;

    @Autowired
    private RedisApi redisApi;

    public Customer getCustomer(String username) {
        Customer customer = redisApi.get("customer:" + username, Customer.class);
        if (customer == null) {
            customer = customerRepository.findByUsername(username);
            redisApi.set("customer:" + username, customer, 60 * 60 * 24);
        }
        return customer;
    }

    public Set<Authority> getCustomerAuthority(String username) {
        Set<Authority> authorities = redisApi.get("authorities:" + username, new TypeReference<Set<Authority>>() {});
        if (authorities == null) {
            authorities = authorityRepository.findAuthoritiesByUsername(username);
            redisApi.set("authorities:" + username, authorities, 60 * 60 * 24);
        }
        return authorities;
    }
}

@Service
public class UserDetailServiceImpl implements UserDetailsService {

    @Autowired
    private CustomerService customerService;

    @Override
    public UserDetails loadUserByUsername(String username) throws UsernameNotFoundException {
        Customer customer = customerService.getCustomer(username);
        if (customer == null) {
            throw new UsernameNotFoundException("用户名不存在！");
        }
        Set<Authority> authorities = customerService.getCustomerAuthority(username);
        List<GrantedAuthority> grantedAuthorities = new ArrayList<>();
        for (Authority authority : authorities) {
            grantedAuthorities.add(new SimpleGrantedAuthority(authority.getName()));
        }
        return new User(customer.getUsername(), customer.getPassword(), grantedAuthorities);
    }
}

4. Controller类：

@Controller
public class FilmController {

    @GetMapping("/detail/{type}/{path}")
    public String detail(@PathVariable("type") String type, @PathVariable("path") String path) {
        // 处理请求
        return "detail";
    }
}

5. pom.xml文件：

<dependencies>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-web</artifactId>
    </dependency>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-thymeleaf</artifactId>
    </dependency>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-data-jpa</artifactId>
    </dependency>
    <dependency>
        <groupId>mysql</groupId>
        <artifactId>mysql-connector-java</artifactId>
    </dependency>
    <dependency>
        <groupId>org.springframework.security</groupId>
        <artifactId>spring-security-core</artifactId>
    </dependency>
    <dependency>
        <groupId>org.springframework.security</groupId>
        <artifactId>spring-security-config</artifactId>
    </dependency>
    <dependency>
        <groupId>org.springframework.security</groupId>
        <artifactId>spring-security-web</artifactId>
    </dependency>
    <dependency>
        <groupId>redis.clients</groupId>
        <artifactId>jedis</artifactId>
    </dependency>
</dependencies>
