BPMX3模拟登录

实现功能只需要输入一个帐号即可登录系统。

需要实现上面的功能需要：

1.编辑imitate.jsp页面

<%@page import="com.hotent.core.util.ContextUtil"%>
<%@page import="com.hotent.platform.model.system.SysUser"%>
<%@page import="org.springframework.security.core.Authentication,
    org.springframework.security.core.context.SecurityContext,
    com.hotent.core.util.AppUtil,
    org.springframework.security.authentication.AuthenticationManager,
    org.springframework.security.core.context.SecurityContextHolder,
    org.springframework.security.web.authentication.WebAuthenticationDetails,
    org.springframework.security.authentication.UsernamePasswordAuthenticationToken"%>
<%@ page language="java" contentType="text/html; charset=utf-8"
    pageEncoding="utf-8"%>
<%
    AuthenticationManager authenticationManager=(AuthenticationManager)AppUtil.getBean("authenticationManager");
    String account=request.getParameter("account");

    UsernamePasswordAuthenticationToken authRequest = new UsernamePasswordAuthenticationToken(account, "");
    authRequest.setDetails(new WebAuthenticationDetails(request));
    SecurityContext securityContext = SecurityContextHolder.getContext();
    Authentication auth = authenticationManager.authenticate(authRequest);
    securityContext.setAuthentication(auth);

    SysUser user=ContextUtil.getCurrentUser();

    out.print(user.getFullname());
%>

调用api验证用户，这里只输入了帐号，密码为空，但是数据库中的密码是使用sha256算法加密的密码，这个时候我们需要实现一个PasswordEncoder。

2.实现PasswordEncoder，这个encoder 始终返回为true，具体实现由用户自己实现。

package com.hotent.platform.service.system.impl;
import org.springframework.security.authentication.encoding.PasswordEncoder;
public class EmptyPasswordEncoder implements PasswordEncoder {
    @Override
    public String encodePassword(String rawPass, Object salt) {
        System.out.println(rawPass);
        return rawPass;
    }
    /**
     * encPass:数据库密码
     * rawPass：原密码
     */
    @Override
    public boolean isPasswordValid(String encPass, String rawPass, Object salt) {
        return true;
    }
}

3.配置app-security.xml.

<security:authentication-manager alias="authenticationManager" >
        <security:authentication-provider user-service-ref="sysUserDao">
            <security:password-encoder  ref="passwordEncoder"/>
        </security:authentication-provider>
    </security:authentication-manager>

    <bean id="passwordEncoder" class="com.hotent.platform.service.system.impl.EmptyPasswordEncoder"></bean>

4.配置imitate.jsp匿名访问。

<property name="anonymousUrls">
            <set>
                <value>/mobileLogin.jsp</value>
                <value>/mobileLogin.ht</value>
                <value>/platform/mobile/lang/changLang.ht</value>
                <value>/loginRedirect.ht</value>
                <value>/login.jsp</value>
                <value>/imitate.jsp</value>
                <value>/login.ht</value>
                <value>/bpmImage</value>
                <value>/platform/bpm/processRun/processImage.ht</value>
                <value>/platform/bpm/processRun/getFlowStatusByInstanceId.ht</value>
                <value>/platform/bpm/processRun/taskUser.ht</value>
                <value>/platform/bpm/taskOpinion/list.ht</value>
                <!-- flex附件上传的 -->
                <value>/platform/bpm/bpmDefinition/getXmlImport.ht</value>
                <value>/mobile/system/mobileLogin.ht</value>
                <value>/mobile/system/mobileLogout.ht</value>
            </set>
        </property>
