注意的10个典型用法
1）多个authentication-provide可以同时使用
2 传统的<security:http>
<security:intercept-url pattern=’/admin/**’ access=’hasRole(‘ROLE_ADMIN’)’/>
<security:intercept-url pattern=’/account/**’ access=’hasRole(‘ROLE_USER’)’ />
<security:intercept-url pattern=’/**’ access=’hasRole(‘ROLE_ANONYMOUS’)’ />
<!– other elements removed for clarity –>
</security:http>
3 可以使用一大堆密码加密器：
aseDigestPasswordEncoder
BasePasswordEncoder
LdapShaPasswordEncoder
Md4PasswordEncoder,
Md5PasswordEncoder
MessageDigestPasswordEncoder
MessageDigestPasswordEncoder
PlaintextPasswordEncoder
ShaPasswordEncoder
4 SPRING security的标签
This content will only be visible to users who have
the ‘supervisor’ authority in their list of <tt>GrantedAuthority</tt>s.
</sec:authorize>
这是根据角色判断是否显示
还可以根据URL判断是否显示
<sec:authorize url=’/admin’>
This content will only be visible to users who are authorized to send requests to the ‘/admin’ URL.
</sec:authorize>
5 方法级的鉴别
@PreAuthorize @PostAuthorize @Secure
要启用上面三者，要
<global-method-security pre-post-annotations=’enabled’ />
这三个是在方法调用前，先鉴别是否有权限使用，比如
｛
@PreAuthorize(“hasRole(‘ROLE_USER’)”)
public void changePassword(String username, password);
｝
感觉这个其实不是很常用
6 同5，可以使用JSR-250 注解去做
<global-method-security jsr250-annotations=”enabled”/>
@RolesAllowed({“ROLE_USER”,”ROLE_ADMIN”})
@PermitAll
@DenyAll
这样使用：
@RolesAllowed({“ROLE_ADMIN”,”ROLE_USER”})
public void deleteUser(String username);
这个东西反正没用到，具体见手册
7 配置open-id,步骤
<label for=’openid_idenifier’>Login</label>:
<input id=’openid_identifier’ name=’openid_identifier’ type=’text’/>
<input type=’submit’ value=’Login’ />
</form>
<http auto-config=’true’>
<openid-login/>
</http>
当然要加上：spring-security-openid.jar
8 spring secruity能使用ldap
<ldap-server ldif=’classpath:my-ldif-file.ldif’ id=’localserver’ />
当然要加上：spring-security-openid.jar
9 使用远程 ldap-server
<ldap-server url=’ldap://myServer/dc=captaindebug,dc=com:389′ id=’ldapExternal’
manager-dn=’uid=admin,ou=users,ou=systems’ manager-password=’s3cret’/>
8和9还没用过，估计配置起来还有更多东西
10 使用https
<http auto-config=’true’ use-expressions=’true’>
<intercept-url pattern=’/login’ requires-channel=’https’/>
</https>
这个比较简单，用requires-channel＝’https’
