備注:此文檔是在2016年整理，沒(méi)在網(wǎng)上發(fā)布，一直在是本地word中記錄，現(xiàn)在遷移到線上。并且文章中是基于xml等文件配置的構(gòu)建項(xiàng)目，所以感覺(jué)很繁瑣。目前可以用springboot替代，并且activiti與springboot整合也是非常簡(jiǎn)單的。
1.maven項(xiàng)目的簡(jiǎn)單介紹
（1）.首先在eclipse中創(chuàng)建一個(gè)maven項(xiàng)目，創(chuàng)建完maven項(xiàng)目之后，最重要的一條就是文件同步，文件同步需要在eclipse中添加一個(gè)文件同步插件叫filesync 。不要和build path中的source目錄搞混。（想想這樣應(yīng)該可以達(dá)到熱部署的效果）
2.開(kāi)始activiti流程設(shè)計(jì)器和rest api接口的搭建
（1）.首先引入需要的jar包，此項(xiàng)目用maven管理，所以編寫pom.xml文件，pom.xml文件內(nèi)容如下

（2）.pom文件編寫好之后，開(kāi)始搭建Spring環(huán)境和springmvc的環(huán)境，因?yàn)閍ctiviti的項(xiàng)目時(shí)基于這兩框架開(kāi)發(fā)的所以在此也用這兩框架作為基礎(chǔ)來(lái)管理bean。首先創(chuàng)建Spring的配置文件beans.xml,其中的內(nèi)包括基礎(chǔ)bean的配置和數(shù)據(jù)庫(kù)連接池的配置等，我在整合的過(guò)程中將activiti的配置文件信息也直接寫到了bean.xml文件中了，其中的信息包括初始化activiti數(shù)據(jù)庫(kù)屬性配置，事務(wù)的配置等等一系列。以下圖片強(qiáng)調(diào)幾個(gè)需要注意的問(wèn)題，（在搭建過(guò)程遇到的問(wèn)題）。

注意：以上配置文件的內(nèi)容主要掃描包的配置

（6）.上面的配置文件寫好之后，配置web.xml文件來(lái)實(shí)例化上下文信息

（7）.下載activiti5.21版本的源碼包(5.17之前的版本源碼中的目錄結(jié)構(gòu)和之后有點(diǎn)不一樣)，解壓之后，找到modules目錄，進(jìn)去之后找activiti-webapp-explorer2在這個(gè)文件夾中找如下文件
將上面紅框中的文件拷貝到自己項(xiàng)目的webapp目錄下。
再繼續(xù)找?src/main/resources/stencilset.json將這個(gè)json文件拷貝到resources文件夾下，其定義了bpmn的相關(guān)構(gòu)成組件的信息。
（8）.準(zhǔn)備基礎(chǔ)服務(wù)類
復(fù)制文件(https://github.com/henryyan/kft-activiti-demo/tree/master/src/main/java/org/activiti/explorer)里面的java文件到自己項(xiàng)目中。
（9）.添加Rest安全認(rèn)證組件SecurityConfiguration類
package org.tzxx.conf;
import org.activiti.rest.security.BasicAuthenticationProvider;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.security.authentication.AuthenticationProvider;
import org.springframework.security.config.annotation.web.builders.HttpSecurity;
import org.springframework.security.config.annotation.web.configuration.EnableWebSecurity;
import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter;
import org.springframework.security.config.annotation.web.servlet.configuration.EnableWebMvcSecurity;
import org.springframework.security.config.http.SessionCreationPolicy;
@Configuration
@EnableWebSecurity
@EnableWebMvcSecurity
public class SecurityConfiguration extends WebSecurityConfigurerAdapter {
????@Bean
????public AuthenticationProvider authenticationProvider() {
????????return new BasicAuthenticationProvider();
????}
????@Override
????protected void configure(HttpSecurity http) throws Exception {
????????http.authenticationProvider(authenticationProvider())
????????????.sessionManagement().sessionCreationPolicy(SessionCreationPolicy.STATELESS).and()
????????????.csrf().disable()
????????????.authorizeRequests()
????????????.anyRequest().authenticated()
????????????.and()
????????????.httpBasic();
????}
}
（10）.寫一個(gè)簡(jiǎn)單的ModelController來(lái)實(shí)現(xiàn)頁(yè)面之間的跳轉(zhuǎn)

以上步驟基本的activiti的web流程設(shè)計(jì)器和rest接口搭建基礎(chǔ)工作就已經(jīng)完畢。下面效果圖：
3.流程設(shè)計(jì)器的漢化
1.先將zh-CN.json放入editor-app\i18n下
2.把editor-app\app.js中的’en’改成’zh-CN’
3.替換stencilset.json
4.如果你已訪問(wèn)過(guò)原先的英文項(xiàng)目，請(qǐng)清除緩存信息
