记录一下最近整理的spring boot项目

项目地址:https://gitee.com/xl0917/spring-boot

1.选择Spring Initializr   一直点击next,直到创建完成

 

2.创建spring boot子模块,创建无任何模板的maven项目

3.项目结构

  1. commone——公共类及工具类存放处,可在该项目中引入其他工具jar包
  2. entity——实体类层
  3. dao——数据持久层
  4. api——service接口,配置double及注册中心可供rpc消费端调用
  5. service——业务逻辑
  6. webapp——web项目url请求入口

4.pom.xml文件

  1. 父类pom文件

6.mybatis.generator插件配置

  1. generatorConfig.xml配置
    <?xml version="1.0" encoding="UTF-8"?>
    <!DOCTYPE generatorConfiguration

    </generatorConfiguration>
  2. 引入文件generator.properties配置
    jdbc.driverClass = com.mysql.jdbc.Driver
    jdbc.url = jdbc:mysql://**.**.***.***:3306/backstage?useUnicode=true&characterEncoding=utf-8&allowMultiQueries=true&zeroDateTimeBehavior=convertToNull&useSSL=false

    module.domain = backstage-entiy
    module.dao = backstage-dao
    
    package.mapper = com.xulong.backstage.dao.mapper
    package.domain = com.xulong.backstage.entity
    driverPath = D:\repository4\mysql\mysql-connector-java\5.1.44\mysql-connector-java-5.1.44.jar
    
    jdk.use_jdk8_time = true

7.shiro框架配置

  1. java类方式配置
    package com.xulong.backstage;
    
    import org.apache.shiro.mgt.SecurityManager;
    import org.apache.shiro.spring.LifecycleBeanPostProcessor;
    import org.apache.shiro.spring.security.interceptor.AuthorizationAttributeSourceAdvisor;

         */
        @Bean("securityManager")
        public DefaultWebSecurityManager newDefaultWebSecurityManager(ShiroUserRealm userUserRealm){
            DefaultWebSecurityManager sManager = new DefaultWebSecurityManager();
            sManager.setRealm(userUserRealm);
            return sManager;
        }
    
        @Bean("shiroFilter")

            fcMap.put("/static/**","anon");
    
            fcMap.put("/**", "authc"); //必须授权才能访问  authc
            bean.setFilterChainDefinitionMap(fcMap);
            //登录成功跳转的url
            bean.setSuccessUrl("/index.html");
            return bean;
        }
        /**
         * 配置shiro生命周期管理器
         * @return
         */
        @Bean("lifecycleBeanPostProcessor")

            return new LifecycleBeanPostProcessor();
        }
    
        /**
         * 配置shiro注解应用
         * */
        @DependsOn(value="lifecycleBeanPostProcessor")

        }
    
        @Bean
        public AuthorizationAttributeSourceAdvisor newAuthorizationAttributeSourceAdvisor(SecurityManager securityManager){

            return bean;
        }
    
    
    
    }
  2. 登录验证类
    package com.xulong.backstage;
    
    import com.xulong.backstage.common.constants.DictCodeConstants;
    import com.xulong.backstage.dao.mapper.UserMapper;
    import com.xulong.backstage.entity.User;
    import org.apache.shiro.authc.*;
    import org.apache.shiro.authc.credential.CredentialsMatcher;
    import org.apache.shiro.authc.credential.HashedCredentialsMatcher;
    import org.apache.shiro.authz.AuthorizationInfo;
    import org.apache.shiro.realm.AuthorizingRealm;
    import org.apache.shiro.subject.PrincipalCollection;
    import org.springframework.beans.factory.annotation.Autowired;
    import org.springframework.stereotype.Service;
    
    /**
     * @author xulong
     * shiro 验证登录等类
     */
    @Service
    public class ShiroUserRealm extends AuthorizingRealm {
    
        @Autowired
        private UserMapper userMapper;
    
        @Override
        protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken token) throws AuthenticationException {
            //1.获取客户端提交的用户信息
            UsernamePasswordToken upToken = (UsernamePasswordToken)token;
            String username = upToken.getUsername();
            upToken.getPassword();
            User user = userMapper.findUserByUserCode(username);
            if(user == null){
                throw new AuthenticationException("用户名或密码不正确!");
            }
            if(DictCodeConstants.DICT_100002_1.equals(user.getUserStatus())){
                throw new AuthenticationException("账户已被冻结,请联系管理员!");
            }
            if(DictCodeConstants.DICT_100002_2.equals(user.getUserStatus())){
                throw new AuthenticationException("账户已被禁用,请联系管理员!");
            }
            SimpleAuthenticationInfo simple =
                    new SimpleAuthenticationInfo(
                            user,  //传入对象后,后续可以在shiro中获取登录用户的对象信息
                            user.getPassword(),
                            getName());
            return simple;//返回给认证管理器
        }
        /**
         * 此方法用于获取用户权限信息----执行权限操作
         */
        @Override
        protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principal) {
    
            return null;
        }
    
        /**
         * 设置凭证匹配器
         */
        @Override
        public void setCredentialsMatcher(CredentialsMatcher credentialsMatcher) {
    //密码验证是否成功方法,比如密码错误有其它操作或者有自己的校验要求 CustomCredentialsMatcher cMatcher = new CustomCredentialsMatcher(); super.setCredentialsMatcher(cMatcher); } }
  3. 密码验证类
    package com.xulong.backstage;
    
    import org.apache.shiro.authc.AuthenticationException;
    import org.apache.shiro.authc.AuthenticationInfo;
    import org.apache.shiro.authc.AuthenticationToken;
    import org.apache.shiro.authc.UsernamePasswordToken;
    import org.apache.shiro.authc.credential.SimpleCredentialsMatcher;
    
    import java.util.Objects;
    
    public class CustomCredentialsMatcher extends SimpleCredentialsMatcher {
    
        @Override
        public boolean doCredentialsMatch(AuthenticationToken token, AuthenticationInfo info) {
            UsernamePasswordToken utoken=(UsernamePasswordToken) token;
            String dbPassword = (String) info.getCredentials();
            String inPassword = new String(utoken.getPassword());
            boolean fals = Objects.equals(dbPassword, inPassword);
            if(fals == false){
                //更改当前用户登录错误次数,当错误次数大于3冻结当前用户
                throw new AuthenticationException("用户名或密码不正确!");
            }
            return fals;
        }
    }

8.thymeleaf部分使用

  1. 例如:当数据库存储时间格式为20190401092416,在网页中想显示为2091-04-01 09:24:16,但是thtmeleaf未提供方法转换,需要我们写一个转换类
  2. DateUtil类写一个格式转换方法
    package com.xulong.backstage.common.util;
    
    import java.text.SimpleDateFormat;
    import java.util.Date;
    
    /**
     * @author xulong
     * @date 2019/03/26
     */

        /** 模式 :yyyyMMddHHmmss */
        public static final String YYYYMMDD_HHMMSS = "yyyyMMddHHmmss";
        /** 模式 :yyyyMMdd */
        public static final String YYYYMMDD = "yyyyMMdd";
        /** 模式 :yyyyMM */
        public static final String YYYYMM = "yyyyMM";
        /** 模式 :HHmmss */
        public static final String HHMMSS = "HHmmss";
        /** 模式 :HHmm */
        public static final String HHMM = "HHmm";
    
        public static final String FORMAT_YMDHMS = "yyyy-MM-dd HH:mm:ss";
    
        public static final String DATE_FORMAT_DAY = "yyyy-MM-dd";
    
        /**
         * 获取当前日期的数字格式
         * 如20190326
         * @return
         */
        public static Long getNowDate(){
            Date date = new Date();
            return Long.valueOf(date2String(date,YYYYMMDD));
        }
    
        /**

        public static Long getNowDateTime(){
            Date date = new Date();
            return Long.valueOf(date2String(date,YYYYMMDD_HHMMSS));

                    return getDateFormat(YYYYMMDD).parse(date);
                } else if (date.length() == 14) {
                    return getDateFormat(YYYYMMDD_HHMMSS).parse(date);
                } else if (date.length() == 6) {

           return new SimpleDateFormat(str);
        }
    
    
    
    }
  3. 在控制层封装DateUtil对象
     @RequestMapping("/index.html")
        public String index(Model model){
            model.addAttribute("dateUtil",new DateUtil());
            Long date = 20160824121425L;
            model.addAttribute("date",date);
            return "index";
        }
  4. html页面中书写方式
    <div class="row" style="text-align:center;font-size: 60px;color: #00aced;margin-top:10%">
                      欢迎来到后台管理页面<br>
                      <span th:text="${dateUtil.longFormat(da,'YYYY-MM-dd HH:mm:ss')}"></span>
                  </div>
  5. 页面显示的内容
