SSM+nginx+tomcat+maven+mysql+redis环境搭建及工程全套配置，实现前后端动静分离

前言

服务器环境搭建

windows开发环境

SSM搭建

加入redis(注解形式)

nginx与tomcat关联配置，完成前后端连接

前言

本次采用前后端分离模式，前端以html、css、js为组成模式，后端以spring全家桶的"手动挡"模式SSM作为基础。nginx启动前端，并管理静态文件，tomcat启动后端，管理动态数据，mysql作为应用数据库。开发环境后端工程采用maven工程，并在后端加入redis缓存。

服务器环境搭建

本次是阿里云服务器，操作系统为ubuntu16.04，JDK和tomcat的安装可参照：

一、安装nginx

nginx可以在线安装，也可以离线安装。在线安装简单，直接。离线装主要针对有些内网环境准备的，且可自定义安装路径。

1.在线安装nginx

sudo apt-get update
sudo apt-get install nginx
sudo apt-get upgrade
配置文件：/etc/nginx/nginx.conf
程序文件：/usr/sbin/nginx
日志：/varlog/nginx
默认虚拟主机：/var/www/html
启动：sudo /etc/init.d/nginx start
停止：sudo /etc/init.d/nginx stop
重启：sudo /etc/init.d/nginx restart
状态：sudo /etc/init.d/nginx status
查看端口占用：lsof -i:80

2.离线安装nginx

①准备环境

gcc:nginx编译依赖gcc环境
apt-get install gcc -c++
pcre:(Perl Compatible Regular Expressions)是一个Perl库，包括 perl 兼容的正则表达式库。nginx的http模块使用pcre来解析正则表达式.
apt-get install -y pcre pcre-devel
# 查看zlib是否安装
dpkg -l | grep zlib
# 解决依赖包openssl安装
sudo apt-get install openssl libssl-dev
# 解决依赖包pcre安装
sudo apt-get install libpcre3 libpcre3-dev
# 解决依赖包zlib安装
sudo apt-get install zlib1g-dev

准备完前期环境后，去nginx官网下载nginx-1.14.0.tar.gz

安装之前需要手动创建上面指定的nginx文件夹,否则make会出错：mkdir /usr/local/nginx

②配置nginx

# 添加nginx组
groupadd unginx
# 创建nginx运行账户unginx并加入到unginx组，不允许unginx用户直接登录系统
useradd -g unginx unginx -s /bin/false
配置防火墙
如果是使用的腾讯服务器，只需要在服务器管理平台添加80端口的安全组就好
服务器则可以设置防火墙：
# 修改防火墙配置：
vi + /etc/sysconfig/iptables
# 添加配置项
-A INPUT -m state --state NEW -m tcp -p tcp --dport 80 -j ACCEPT
# 重启防火墙
service iptables restart
cd /usr/local/nginx-1.14.0
./configure --prefix=/usr/local/nginx
make && make install

cd /usr/local/nginx/sbin
检查nginx是否安装成功
./nginx -t
正确结果显示：
nginx: the configuration file /usr/local/nginx/conf/nginx.conf syntax is ok
nginx: configuration file /usr/local/nginx/conf/nginx.conf test is successful

③启动nginx

cd /usr/local/nginx
sbin/nginx
ps -ef | grep nginx

重启nginx：sbin/nginx -s reload
停止：sbin/nginx -s stop

访问：http://hadoop01
即可到nginx欢迎页

二、安装mysql

直接在线安装：apt-get install mysql-server

输入 y ，下载安装时会出现要求设置密码的界面：

输入自己想设置的密码，之后再次输入确认密码。完成之后如下图：

启动mysql：service mysql start，启动后检验：ps -ef | grep mysql

打开数据库，mysql -uroot -p，mysql -uroot -p，输入设置的密码

设置mysql允许远程访问，首先编辑文件/etc/mysql/mysql.conf.d/mysqld.cnf：

sudo vi /etc/mysql/mysql.conf.d/mysqld.cnf，注释掉bind-address = 127.0.0.1：

保存退出，然后进入mysql服务，执行授权命令：
grant all on *.* to root@'%' identified by '你的密码' with grant option;
flush privileges;
然后执行quit命令退出mysql服务，执行如下命令重启mysql：
service mysql restart
数据库就可以被远程连接了。

三、安装redis

直接在线安装redis：sudo apt-get install redis-server

安装完成后，需要手动启动下：redis-server，验证启动redis-cli,输入命令：keys *

配置远程访问：vim /etc/redis/redis.conf，#bind 127.0.0.1注释掉

配置密码：requirepass abcd，设置密码为abcd

输入密码：auth 密码

修改后重启服务：/etc/init.d/redis-server restart

redis安装完毕。

到此，服务器环境准备完毕。

windows开发环境

windows开发环境参照之前博客：https://blog.csdn.net/qq_36632174/article/details/101699311

eclipse配置maven库参照：https://blog.csdn.net/qq_36632174/article/details/101704421

SSM搭建

首先确定，Maven工程结构，如图：

创建一个maven web工程，在resources文件夹下创建框架文件(框架文件名可以自己定义)

spring-mybatis.xml：spring与mybatis结合；

spring-mvc.xml：spring与前端的结合；

redis.properties：redis基础参数；

jdbc.properties：mysql基础参数；

generatorConfig.xml：mybatis生成工具。

sqlmap文件夹下存放mybatis的SQL文件，其它几个包分别是controller层、dao层、model(实例)层、service接口层和service实现类。

创建好以上工程结构后，首先在pom.xml中引入需要的maven包，jar包加载到指定的maven库中：

这是简单版的mybatis配置，集成了mysql和redis数据库，整合了mybatis的.xml文件格式的SQL，整合了Dao文件。企业版的配置请参照：SSM企业版：多数据源+activity+事务+定时任务()

如果是前后端分离，由nginx管理前端文件，html视图解析器、jsp视图解析器及最下面的<mvc:resources **>可以去掉。

想操作generatorConfig.xml文件，先在eclipse的Marketplace(help->eclipse Marketplace)中下载小黑鸟工具

下载好之后，右键点击generatorConfig.xml会出现小黑鸟标志，在配置好文件以下内容后就可以通过此工具直接生成出实例、sql文件、Dao层的初始文件。

generatorConfig.xml配置如下：

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE generatorConfiguration
PUBLIC "-//mybatis.org//DTD MyBatis Generator Configuration 1.0//EN"
"http://mybatis.org/dtd/mybatis-generator-config_1_0.dtd">

#定义最大连接数
maxActive=50
#定义最大空间
maxIdle=300
#定义最小空间

redis.maxWait=60000
redis.maxActive=6000
# 在borrow一个jedis实例时，是否提前进行validate操作；如果为true，则得到的jedis实例均是可用的
redis.testOnBorrow=true
redis.testOnReturn=false

# 当客户端闲置闲置多少秒后，断开连接，如果指定为0，表示关闭该功能
redis.timeout=1800
#缓存清除的时间单位是秒，7776000s=90天，90天清理一次缓存
redis.expiration=7776000

log4j.properties：

#定义LOG输出级别
log4j.rootLogger=INFO,Console,File
#定义日志输出目的地为控制台
log4j.appender.Console=org.apache.log4j.ConsoleAppender
log4j.appender.Console.Target=System.out
#可以灵活地指定日志输出格式，下面一行是指定具体的格式
log4j.appender.Console.layout = org.apache.log4j.PatternLayout
log4j.appender.Console.layout.ConversionPattern=[%c] - %m%n

#文件大小到达指定尺寸的时候产生一个新的文件
log4j.appender.File = org.apache.log4j.RollingFileAppender
#指定输出目录
log4j.appender.File.File = logs/harbour.log
#定义文件最大大小
log4j.appender.File.MaxFileSize = 10MB
# 输出所以日志，如果换成DEBUG表示输出DEBUG以上级别日志
log4j.appender.File.Threshold = ALL
log4j.appender.File.layout = org.apache.log4j.PatternLayout
log4j.appender.File.layout.ConversionPattern =[%p] [%d{yyyy-MM-dd HH\:mm\:ss}][%c]%m%n

以上各种配置文件可以根据不同需求进行修改，以上后台工程配置完成，在eclipse中配置好tomcat(参照之前博客：Java基础-开发环境(windows+jdk+tomcat+maven+mysql))，启动配置好的工程，控制台不报错表示配置正确。数据库创建测试表，根据generatorConfig工具生成实例、Dao文件和sql文件后，写好controller文件、service接口和service实现类，一般前后端分离的controller最终返回给前端的是json字符串数据，具体写法网上很多，此篇不做介绍。

其次样例的调用关系：controller->service接口>service实现类->Dao文件，传参实例->映射sql文件，写好后，可以用Postman工具，测试后台配置的url是否能请求成功，例如后台url为：http://localhost:8080/user/login，login查询用户是否存在，如果用户存在，则返回查询到的数据。

controller.java样例，查询用户：

@Controller
@RequestMapping("/user")
public class UserController {

private final Log logger = LogFactory.getLog(this.getClass());

@Resource
private LoginService systemUserLoginService;

@RequestMapping(value = "/login", method = RequestMethod.POST)
public void login(HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse) {

JSONObject response = new JSONObject();
        HttpSession session = httpServletRequest.getSession();
        String username = httpServletRequest.getParameter("username");
        String password = httpServletRequest.getParameter("password");
        String suDeviceSn = httpServletRequest.getParameter("suDeviceSn");
        String suClientId = httpServletRequest.getParameter("suClientId");
        JSONObject jsonObject = new JSONObject();
        String message = ParameterConstant.LOGIN_SUCCESS;
        try {
            jsonObject = systemUserLoginService.login(username, password, suDeviceSn, suClientId);
        } catch (Exception e) {
            logger.error(MessageConstant.LOGIN_FAILURE, e);
            e.printStackTrace();
            message = e.getMessage();
        }
        // 登录成功保存session
        // 用户名
        session.setAttribute(ParameterConstant.USERNAME, username);
        // 登录用户信息
        session.setAttribute(ParameterConstant.LOGIN_USER, jsonObject.getJSONObject(ParameterConstant.USER));
        // 前端权限
        session.setAttribute(ParameterConstant.FPERMISSION, jsonObject.getJSONArray(ParameterConstant.FPERMISSION));
        // 后台权限
        session.setAttribute(ParameterConstant.BPERMISSION, jsonObject.getJSONArray(ParameterConstant.BPERMISSION));
        response.put(ParameterConstant.LOGIN_MESSAGE, message);
        response.put(ParameterConstant.CONTENT, jsonObject);
        // httpServletResponse.addHeader("Access-Control-Allow-Origin", "*");
        /*httpServletResponse.addHeader("Access-Control-Allow-Credentials", "true");*/
        logger.info(session.getAttribute(ParameterConstant.LOGIN_USER));
        CommonFunction.reponseResult(httpServletResponse, response.toString());

}

当后端controller定义为http://localhost:8080/user/login时，前端ajax部分必须对应URL与controller相同以完成映射：

以下省略··············

加入redis(注解形式)

在前面的spring-mybatis.xml配置文件中已经加入redis相关配置，还需要在Java中加入配置文件，如下：

/**
* 以Spring与配置文件来管理的redis缓存配置类
* @author wang
*
*/
@Configuration
@EnableCaching
public class RedisCacheConfig extends CachingConfigurerSupport {
   private volatile JedisConnectionFactory mJedisConnectionFactory;
   private volatile RedisTemplate<String, String> mRedisTemplate;
   private volatile RedisCacheManager mRedisCacheManager;

   public RedisCacheConfig() {
       super();
   }

public RedisCacheConfig(JedisConnectionFactory mJedisConnectionFactory, RedisTemplate<String,String> mRedisTemplate,
           RedisCacheManager mRedisCacheManager) {
       super();
       this.mJedisConnectionFactory = mJedisConnectionFactory;
       this.mRedisTemplate = mRedisTemplate;
       this.mRedisCacheManager = mRedisCacheManager;
   }

public JedisConnectionFactory redisConnectionFactory() {
return mJedisConnectionFactory;
}

public RedisTemplate<String, String> redisTemplate(RedisConnectionFactory cf) {
return mRedisTemplate;
}

public CacheManager cacheManager(RedisTemplate<?, ?> redisTemplate) {
       return mRedisCacheManager;
   }

   @Bean
   public KeyGenerator customKeyGenerator() {
       return new KeyGenerator() {
           @Override
           public Object generate(Object o, Method method, Object... objects) {
               StringBuilder sb = new StringBuilder();
               sb.append(o.getClass().getName());
               sb.append(method.getName());
               for (Object obj : objects) {
                   sb.append(obj.toString());
               }
               return sb.toString();
           }
       };
   }
}

完成以上配置，在service实现类中，可通过@Cacheable注解完成缓存，示例如下：

@Service
@Transactional(propagation = Propagation.REQUIRED, rollbackFor = Exception.class)
public class UserServiceImpl implements UserService {

@Resource
private UserInfoDao userInfoDao;

// 增加用户数据
   @Override
   @CacheEvict(value = { "insert" }, allEntries = true)
   public Integer insert(UserInfo userInfo) {
       return userInfoDao.insertSelective(userInfo);
   }

// 根据主键删除用户数据
   @Override
   @CacheEvict(value = {"selectByPrimaryKey"}, allEntries = true)//allEntries=true表示清理所有缓存
   public Integer delete(Integer uid) {
       return userInfoDao.deleteByPrimaryKey(uid);
   }

// 根据主键选择更新数据
   @Override
   /*@CachePut("updateByPrimaryKeySelective")*/
   @CacheEvict(value = {"selectByPrimaryKey" }, key="#userInfo.getId()")
   public Integer updateByPrimaryKeySelective(UserInfo userInfo) {
       return userInfoDao.updateByPrimaryKeySelective(userInfo);
   }

// 根据主键查询数据
   @Override
   @Cacheable(value="selectByPrimaryKey", key="#uid")
   public UserInfo select(Integer uid) {
       return userInfoDao.selectByPrimaryKey(uid);
   }

}

@Cacheable主要针对方法配置，能够根据方法的请求参数对其结果进行缓存
@CacheEvict：即应用到移除数据的方法上，如删除方法。@Cacheable和@CacheEvict，这两个注解可以允许方法触发缓存或者缓存抽取。
@CacheEvict：主要针对方法配置，能够根据一定的条件对缓存进行清空
@CachePut()：应用到写数据的方法上，如新增/修改方法。@CachePut 注释，这个注释可以确保方法被执行，同时方法的返回值也被记录到缓存中
@CachePut()：主要针对方法配置，能够根据方法的请求参数对其结果进行缓存，和 @Cacheable 不同的是，它每次都会触发真实方法的调用

产生缓存数据后，可通过命令查看缓存，以下为windows环境下查看：

启动redis客户端：redis-cli.exe -h 127.0.0.1 -p 6379

nginx与tomcat关联配置，完成前后端连接

由于要做动静分离，前端工程其实就是文件目录，只包含html、js、css、图片等静态文件：

可根据实际情况，自定义文件名称。

如果是本地环境可参照以下配置：

找到nginx目录下nginx_home/conf路径下nginx.conf文件，配置如下：

user root;
worker_processes 1;

#error_log logs/error.log;
#error_log logs/error.log notice;
#error_log logs/error.log info;

#pid logs/nginx.pid;

events {
worker_connections 1024;
}

http {
    include       mime.types;
    default_type application/octet-stream;
   client_max_body_size 100M;
    #log_format main '$remote_addr - $remote_user [$time_local] "$request" '
    #                  '$status $body_bytes_sent "$http_referer" '
    #                  '"$http_user_agent" "$http_x_forwarded_for"';

#access_log logs/access.log main;

sendfile on;
#tcp_nopush on;

#keepalive_timeout 0;
keepalive_timeout 65;

#gzip on;

server {
listen 80;
server_name localhost;

#把前端工程，放到路径D盘的HBuilderProject下，nginx就可以找到前端工程文件，并加载静态文件，在浏览器能正常显示

location ~ .*\.(html|js|css|ico|png|bmp|jpg|eot|jpeg|svg|ttf|woff|gif|swf|xlsx|docx|pdf|apk) {
        root D:/HBuilderProject/;
        expires 10d;
        }

# 映射后端tomcat下工程web_project_resources

location /web_project_resources/ {
                proxy_redirect off;
                proxy_set_header Host $host;
                proxy_set_header X-Real-IP $remote_addr;
                proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
                proxy_connect_timeout 5;
                proxy_send_timeout 30;
                proxy_read_timeout 10;
                proxy_pass http://127.0.0.1:8080/web_project_resources/;
        }

}

配置完成后，在本地启动nginx。

对maven打包，打成web_project_resources.war包后，放在tomcat路径的webapps下，启动tomcat，在浏览器访问url，就可以完成前后端连接。当启动nginx后，前端静态文件就可以在浏览器显示(比如：html、js实现的逻辑、css样式和图片、字体等)，但是不启动tomcat则无法连接到spring后台，也无法连接到数据库获取数据。所以当启动tomcat，前后端url映射完成后，数据库数据才能传到前端浏览器画面正常显示。如果是测试服务器，无需配置域名的，也可参照本地nginx配置，只需要更换ip即可。

以上就是个人版全套SSM+nginx+tomcat+mysql+redis配置与实现，实现前后端分离，动静分离，并加入redis缓存。
