Spring Security 2配置精讲 上(9)
时间:2011-10-16
Java代码
@Entity
@Cache(usage = CacheConcurrencyStrategy.READ_WRITE)
public class Role {
@Id
@GeneratedValue
private Integer id;
private String name;
// setters and getters
}
@Entity
@Cache(usage = CacheConcurrencyStrategy.READ_WRITE)
public class Role {
@Id
@GeneratedValue
private Integer id;
private String name;
// setters and getters
}
请注意这里的Annotation的写法。同时，我为User和Role之间配置了缓存。并且将他们之间的关联关系设置的lazy属性设置成false，从而保证在User对象取出之后的使用不会因为脱离session的生命周期而产生lazy loading问题。
2. 使User类实现UserDetails接口
接下来，我们让User类去实现UserDetails接口：
Java代码
@Entity
@Proxy(lazy = false)
@Cache(usage = CacheConcurrencyStrategy.READ_WRITE)
public class User implements UserDetails {
private static final long serialVersionUID = 8026813053768023527L;
@Id
@GeneratedValue
private Integer id;
private String name;
private String password;
private boolean disabled;
@ManyToMany(targetEntity = Role.class, fetch = FetchType.EAGER)
@JoinTable(name = "user_role", joinColumns = @JoinColumn(name = "user_id"), inverseJoinColumns = @JoinColumn(name = "role_id"))
@Cache(usage = CacheConcurrencyStrategy.READ_WRITE)
private Set<Role> roles;
/**
* The default constructor
*/
public User() {
}
/* (non-Javadoc)
* @see org.springframework.security.userdetails.UserDetails#getAuthorities()
*/
public GrantedAuthority[] getAuthorities() {
List<GrantedAuthority> grantedAuthorities = new ArrayList<GrantedAuthority>(roles.size());
for(Role role : roles) {
grantedAuthorities.add(new GrantedAuthorityImpl(role.getName()));
}
return grantedAuthorities.toArray(new GrantedAuthority[roles.size()]);
}
/* (non-Javadoc)
* @see org.springframework.security.userdetails.UserDetails#getPassword()
*/
public String getPassword()
