2017.6.8 spring-ldap基本使用总结

时间:2022-10-15 08:33:08

之前学习过spring-ldap的官方文档:2017.4.10 spring-ldap官方文档学习

现在是对实际使用的spring-ldap及使用过程中遇到的问题,进行总结。

1.spring-ldap的pom依赖

         <!-- 添加Spring-ldap-->
<dependency>
<groupId>org.springframework.ldap</groupId>
<artifactId>spring-ldap-core</artifactId>
<version>2.3.1.RELEASE</version>
</dependency>

下面的网址是spring的ldap页,里面有一个quick start。其中显示了spring-ldap最近的版本,并且勾选不同的版本,会自动生成依赖。

http://projects.spring.io/spring-ldap/

2.ldapTemplate的生成--方式1自动注入

2.1 spring-ldap声明

 <beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:ldap="http://www.springframework.org/schema/ldap"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
http://www.springframework.org/schema/ldap http://www.springframework.org/schema/ldap/spring-ldap.xsd">

2.2 ldapTemplate bean

 <context:property-placeholder location="classpath:/ldap.properties" />
<ldap:context-source id="contextSource"
password="${sample.ldap.password}"
url="${sample.ldap.url}"
username="${sample.ldap.userDn}"
base="${sample.ldap.base}" />
<ldap:ldap-template id="ldapTemplate" context-source-ref="contextSource"/>

或者

 <bean id="contextSource"
class="org.springframework.ldap.core.support.LdapContextSource">
<property name="url" value="${sample.ldap.url}" />
<property name="base" value="${sample.ldap.base}" />
<property name="userDn" value="${sample.ldap.userDn}" />
<property name="password" value="${sample.ldap.password}" />
</bean> <bean id="ldapTemplate" class="org.springframework.ldap.core.LdapTemplate">
<constructor-arg ref="contextSource" />
</bean>

2.3 使用

 @Autowired
private LdapTemplate ldapTemplate;

3.ldapTemplate的生成--方式2代码生成

 public LdapTemplate getLdapTemplate(){
LdapTemplate template = null;
try {
LdapContextSource contextSource = new LdapContextSource();
contextSource.setUrl(getSync_ldap_url());
contextSource.setBase(getSync_ldap_base());
contextSource.setUserDn(getSync_ldap_userDn());
contextSource.setPassword(getSync_ldap_password());
contextSource.setPooled(false);
contextSource.afterPropertiesSet(); // important
template = new LdapTemplate(contextSource);
}catch (Exception e){
e.printStackTrace();
}
return template;
}

4.spring-ldap的使用

api的使用在上次的文档中已经学习过了:2017.4.10 spring-ldap官方文档学习

一些简单示例:

/**
* 动态创建dn
* @param user
* @return
*/
private Name buildDn(User user) {
return LdapNameBuilder.newInstance()
.add("ou", "Users")
.add("uid",user.getFdUserid().toString())
.build();
} /**
* 在ldap里更新用户
* @param user
*/
private void updateUser(User user) {
Name dn = buildDn(user);
getLdapTemplate().rebind(dn, null, buildAttributes(user));
} /**
* 在ldap里删除用户
* @param user
*/
private void deleteUser(User user) {
Name dn = buildDn(user);
getLdapTemplate().unbind(dn);
} /**
* 在ldap里创建用户
* @param user
*/
private void createUser(User user) {
Name dn = buildDn(user);
getLdapTemplate().bind(dn, null, buildAttributes(user));
} /**
* 动态构建属性
* @param user
* @return
*/
private Attributes buildAttributes(User user) { Attributes attrs = new BasicAttributes();
try {
BasicAttribute objectclass = new BasicAttribute("objectclass");
objectclass.add("top");
objectclass.add("posixAccount");
objectclass.add("inetOrgPerson");
attrs.put(objectclass); attrs.put("userPassword", user.getFdLdapPassword() == null ? "" : user.getFdLdapPassword());
attrs.put("cn", user.getFdUsername() + "@" + user.getFdTenantName());
attrs.put("sn", user.getFdUsername() + "@" + user.getFdTenantName());
attrs.put("displayName", user.getFdDisplayName()== null? "":user.getFdDisplayName());
attrs.put("homeDirectory", "/root");
attrs.put("uidNumber", "0");
attrs.put("uid", user.getFdUserid().toString());
attrs.put("gidNumber", "0");
}catch (Exception e){
e.printStackTrace();
}
return attrs;
}
