Saiku调用WS接口

关于saiku集成系统单点登录告一段落，始终没想好怎么去做，主要是因为saiku有自己的权限定义，一直没想好关于saiku本身的权限信息以及用户信息怎么处理(在这里笔者希望已实现saiku单点登录的大佬不吝赐教，感激~)

这里实现了在saiku源码里面调用公司内部的WS接口来验证登录时的密码信息（因为saiku本身未使用dubbo,所以无法直接通过maven引入dubbo包去调用接口）

如果已查看了saiku登录源码追踪（十三）我们就已经大概知道saiku登录时代码执行过程啦，接下来我们就来更改这里的密码校验，调用其他组件的WS接口验证登录

>>调用WS接口

1.在saiku-webapp项目下 找到 WEB-INF/applicationContext-spring-security-jdbc.xml 文件

作出以下更改，替换原来的bean信息，将原来的 org.springframework.security.authentication.dao.DaoAuthenticationProvider 类 替换为自己定义的 org.saiku.service.util.security.authentication.UmServiceProvider 类

 <!-- 
　　<bean id="daoAuthenticationProvider"
          class="org.springframework.security.authentication.dao.DaoAuthenticationProvider">
        <property name="userDetailsService">
            <ref bean="userDetailsService" />
        </property>
        <property name="passwordEncoder">
            <ref bean="passwordEncoder" />
        </property>
    </bean> 
 -->
 <bean id="daoAuthenticationProvider"
          class="org.saiku.service.util.security.authentication.UmServiceProvider">
        <property name="userDetailsService">
            <ref bean="userDetailsService" />
        </property>
        <property name="passwordEncoder">
            <ref bean="passwordEncoder" />
        </property>
    </bean>

　

2.org.saiku.service.util.security.authentication.UmServiceProvider　类定义在saiku-service项目下的 对应包（org.saiku.service.util.security.authentication.）路径下

内容如下：（内容上基本语原来的DaoAuthenticationProvider 保持一致，更改密码校验方法：additionalAuthenticationChecks(UserDetails userDetails,UsernamePasswordAuthenticationToken authentication))

思路： 注释掉源代码中的密码校验方法passwordEncoder.isPasswordValid，

　　　 新增自己的密码校验方法： validatePassword(UserDetails userDetails,UsernamePasswordAuthenticationToken authentication,Object salt)

/*密码校验思路：
1.先判断密码是不是固定密码值，从properties文件中获取的自定义密码信息（我这里是因为嵌入系统时有用到固定密码对应用户以及角色信息气分享saiku数据信息所以才有，如果不需要可以去掉第一个if中的判断 fixedPassword）　 　
2.再判断密码是否满足 WS接口（WS是公司自定义的相关接口信息，通过jar包引入saiku去调用的，下面会做出相应解析） 　　　
3.以上两种都不符合时，调用saiku自己的密码校验，如果失败就校验失败了。（以上任意一种校验方式成功都会成功登录哦)

3.关于从配置文件中读取固定密码信息。 saikuUser.properties中读取 fixedPassword

在saiku-service中新建Util类：  /saiku-service/src/main/java/org/saiku/service/util/GetFixedPasswordUtil.java

package org.saiku.service.util;

import java.io.FileInputStream;
import java.io.InputStream;
import java.rmi.RemoteException;
import java.util.Properties;

import org.apache.commons.logging.Log;
import org.apache.commons.logging.LogFactory;

import com.imodule.ws.soa.um.UmSoaPortTypeProxy;
import com.imodule.ws.soa.um.result.xsd.UmLoginResult;

/**
 * Get password from properties file,for validate password.
 * ps：  properties file path keep on with this Class path .
 * @author S0111
 *
 */
public class GetFixedPasswordUtil {
	
	private String SAIKU_USER_PASSWORD = "saikuUserPassword";
	private String FILE_NAME = "saikuUser.properties";
//	FileInputStream in = null;
	InputStream ins = null;
	String  saikuUserPassword = null;
	protected final Log logger = LogFactory.getLog(getClass());
	
	/**
	 * Get local password from properties file.
	 * @return
	 */
	public String getSaikuUserPassword(){
		try{
			Properties properties = new Properties();
//			ins = new FileInputStream(this.getClass().getResource("/").getPath()+FILE_NAME);
//			ins = getClass().getResourceAsStream(FILE_NAME);
			ins = GetFixedPasswordUtil.class.getClassLoader().getResourceAsStream(FILE_NAME);
			properties.load(ins);
			saikuUserPassword = properties.getProperty(SAIKU_USER_PASSWORD);
			logger.debug("GetFixedPasswordUtil - getSaikuUserPassword ,read the properties file,password value is:"+saikuUserPassword);
		}catch(Exception e){
			logger.debug("GetFixedPasswordUtil - getSaikuUserPassword failed, Caused by:"+e);
			e.printStackTrace();
		}finally{
			if(ins != null){
				try{
					ins.close();
				}catch(Exception e){
					logger.debug("GetFixedPasswordUtil - getSaikuUserPassword failed, Caused by:"+e);
					e.printStackTrace();
				}
			}
		}
		return saikuUserPassword;
		
	}

}

　　

相应的在 saiku-service项目中的 src/main/resources目录下新建properties文件： /saiku-service/src/main/resources/saikuUser.properties  (这里表示不管啥用户只有是saiku有的用户，使用密码saiku123都能登录saiku)

saikuUserPassword=saiku123

　　

4.关于调用其他WS接口验证

首先需要得到WS接口地址信息： http://11.22.33.44:8080/demo-ws/services/demo-soa?wsdl     #这只是个示例地址，每个公司提供的接口地址都不同

验证地址： 在浏览器中输入  http://11.22.33.44:8080/demo-ws/services/demo-soa?wsdl 去访问，正确的WS接口信息会返回 <wsdl:definitions xmlns:wsd ... 等类似信息

使用Eclipse新建Maven项目 saiku-um-ws  (项目命名随自己啦嘻嘻)

右击新建的羡慕 saiku-um-ws  -->  new   --> others  --> 选中下图中的 Web Service Client --> 点击 next

进入如下页面，在Service definition 处输入WS接口地址信息：http://11.22.33.44:8080/demo-ws/services/demo-soa?wsdl   然后点击finish 即可

再进去看就会看到新建的maven项目 saiku-um-ws已经被填充好了

pom.xml中内容如下：

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

  <groupId>com.saiku.ws</groupId>
  <artifactId>saiku-um-ws</artifactId>
  <version>1.0</version>
  <packaging>jar</packaging>

  <name>saiku-um-ws</name>
  <url>http://maven.apache.org</url>

  <properties>
    <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
  </properties>

  <dependencies>
    <dependency>
      <groupId>junit</groupId>
      <artifactId>junit</artifactId>

		<artifactId>xml-apis</artifactId>
		<version>1.4.01</version>
	</dependency>
	
	<dependency>
	    <groupId>wsdl4j</groupId>
	    <artifactId>wsdl4j</artifactId>
	    <version>1.5.1</version>
	</dependency>
	
	<dependency>
	    <groupId>soap</groupId>
	    <artifactId>soap</artifactId>
	    <version>2.3</version>
	</dependency>
  </dependencies>
</project>

　　

将saiku-um-ws项目打包：  mvn  clean  install

再将saiku-um-ws相关的依赖引入 saiku-service项目中的 pom.xml即可

　　<!-- add in  2019-03-11,for validate password use other system -->
   <dependency>
       <groupId>com.saiku.ws</groupId>
	  <artifactId>saiku-um-ws</artifactId>
	  <version>0.0.1-SNA</version>
    </dependency>
    
     <dependency>
	<groupId>xml-apis</groupId>
	<artifactId>xml-apis</artifactId>
	<version>1.4.01</version>
    </dependency>

　　

最后，重新编译整个saiku项目, mvn clean install 

获取saiku-server下的 target/dist/saiku-server  双击脚本saiku-start.bat 文件 启动saiku就可以啦~~~~~~~~~
