二、常用的命名空间

• Thymeleaf命名空间

  <html lang="en" xmlns:th="http://www.thymeleaf.org">
  

• Shiro

  	<html lang="en" xmlns:th="http://www.thymeleaf.org"
    xmlns:shiro="http://www.pollix.at/thymeleaf/shiro">
  

• XxxMapper

  <?xml version="1.0" encoding="UTF-8" ?>
  <!DOCTYPE mapper
          PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN"
          "http://mybatis.org/dtd/mybatis-3-mapper.dtd">
  
  <mapper namespace="henu.soft.xiaosi.mapper.EmployeeMapper">
  

三、常用的properties、yml配置

• application.properties

# 配置映射路径
server.servlet.context-path=/

# 国际化配置，参数为配置文件的位置
spring.messages.basename=i18n/login

# 设置日期格式
spring.mvc.format.date=yyyy/MM/dd

# 关闭Thymeleaf缓存
spring.thymeleaf.cache=false 

• log4j.properties

# LOG4J配置
log4j.rootCategory=DEBUG, stdout

# 控制台输出
log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=%d{yyyy-MM-dd HH:mm:ss,SSS} %5p %c{1}:%L - %m%n

• application.yml

Druid

spring:
  datasource:
    username: root
    password: 720720
    # ?serverTimezone=UTC解决时区的报错
    url: jdbc:mysql:///springboot?serverTimezone=UTC&useUnicode=true&chararcterEncoding=utf-8
    driver-class-name: com.mysql.cj.jdbc.Driver
    type: com.alibaba.druid.pool.DruidDataSource

    #Spring Boot 默认是不注入这些属性值的，需要自己绑定
    #druid 数据源专有配置
    initialSize: 5
    minIdle: 5
    maxActive: 20
    maxWait: 60000
    timeBetweenEvictionRunsMillis: 60000
    minEvictableIdleTimeMillis: 300000
    validationQuery: SELECT 1 FROM DUAL
    testWhileIdle: true
    testOnBorrow: false
    testOnReturn: false
    poolPreparedStatements: true

    #配置监控统计拦截的filters，stat:监控统计、log4j：日志记录、wall：防御sql注入
    #如果允许时报错  java.lang.ClassNotFoundException: org.apache.log4j.Priority
    #则导入 log4j 依赖即可，Maven 地址：https://mvnrepository.com/artifact/log4j/log4j
    filters: stat,wall,log4j
    maxPoolPreparedStatementPerConnectionSize: 20
    useGlobalDataSourceStat: true
    connectionProperties: druid.stat.mergeSql=true;druid.stat.slowSqlMillis=500

MyBatis

#MyBatis
mybatis:
  # 起别名
  type-aliases-package: henu.soft.xiaosi.pojo
  mapper-locations: classpath:mybatis/mapper/*.xml

XxxMappeer.xml

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE mapper
        PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN"
        "http://mybatis.org/dtd/mybatis-3-mapper.dtd">

<mapper namespace="henu.soft.xiaosi.mapper.EmployeeMapper">
    <resultMap id="EmployeeMap" type="Employee">
        <id property="id" column="id"/>
        <result property="lastName" column="lastName"/>
        <result property="email" column="email"/>
        <result property="gender" column="gender" />
        <result property="birth" column="birth"/>
        <association property="department" javaType="Department">
            <id property="id" column="id"/>
            <result property="departmentName" column="departmentName"/>
        </association>

    </resultMap>

<!--    查询所有的员工和部门-->
    <select id="getEmployees" resultMap="EmployeeMap">
        SELECT e.id,e.lastName,e.email,e.gender,d.departmentName,e.birth
        FROM employee e,department d
        WHERE e.departmentId = d.id;

    </select>
<!--    新增一个员工-->
    <select id="save" parameterType="Employee" >
        insert into employee(lastName,email,gender,departmentId,birth)
        values(#{lastName},#{email},#{gender},#{department.id},#{birth});
    </select>
<!--    查询一个员工-->
    <select id="getEmployeeById" resultType="Employee" parameterType="Integer">
        select * from employee where id = #{id}
    </select>
    <select id="delete" parameterType="int" >
        delete from employee where id = #{id}
    </select>

</mapper>

四、常用组件

1. MyMvcConfig

package henu.soft.xiaosi.config;

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.LocaleResolver;
import org.springframework.web.servlet.config.annotation.InterceptorRegistry;
import org.springframework.web.servlet.config.annotation.ViewControllerRegistry;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurer;

import java.util.Locale;

@Configuration
public class MyMvcConfig implements WebMvcConfigurer {
    
    
    //自定义MVC跳转器组件
    @Override
    public void addViewControllers(ViewControllerRegistry registry) {
    
    
        registry.addViewController("/").setViewName("index");
        registry.addViewController("/index.html").setViewName("index");
        registry.addViewController("/main.html").setViewName("dashboard");
    }

    //自定义国际化组件,装配组件
    @Bean
    public LocaleResolver localeResolver(){
    
    
        return new MyLocaleResolver();
    }


    /*
    //自定义拦截器组件，装配组件
    @Override
    public void addInterceptors(InterceptorRegistry registry) {
        registry.addInterceptor(new MyLoginHandlerInterceptor())
                .addPathPatterns("/**")
                .excludePathPatterns("index.html","/","/user/login","/assert/**","/assert/css/**","/assert/js/**");
    }

     */
}

2. MyLocalResolver国际化

<a class="btn btn-sm" th:href="@{/index.html(l='zh_CN')}">中文</a>
<a class="btn btn-sm" th:href="@{/index.html(l='en_US')}">English</a>

package henu.soft.xiaosi.config;

import org.springframework.web.servlet.LocaleResolver;
import org.thymeleaf.util.StringUtils;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.util.Locale;

public class MyLocaleResolver implements LocaleResolver {
    
    

    //解析请求
    @Override
    public Locale resolveLocale(HttpServletRequest httpServletRequest) {
    
    
        //获取语言请求参数
        String language = httpServletRequest.getParameter("l");
        //默认
        Locale locale = Locale.getDefault();

        //如果请求的连接携带了国际化语言参数
        if(!StringUtils.isEmpty(language)){
    
    
            String[] split = language.split("_");
            //拿出来参数地区-语言
            return new Locale(split[0], split[1]);
        }


        return locale;
    }

    @Override
    public void setLocale(HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse, Locale locale) {
    
    

    }
}

3. DruidConfig

package henu.soft.xiaosi.config;

import com.alibaba.druid.pool.DruidDataSource;
import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

import javax.sql.DataSource;

@Configuration
public class DruidConfig {
    
    

    /*
      将自定义的 Druid数据源添加到容器中，不再让 Spring Boot 自动创建
      绑定全局配置文件中的 druid 数据源属性到 com.alibaba.druid.pool.DruidDataSource从而让它们生效
      @ConfigurationProperties(prefix = "spring.datasource")：作用就是将 全局配置文件中
      前缀为 spring.datasource的属性值注入到 com.alibaba.druid.pool.DruidDataSource 的同名参数中
    */
    @ConfigurationProperties(prefix = "spring.datasource")
    @Bean
    public DataSource druidDataSource() {
    
    
        return new DruidDataSource();
    }
}

4. ShiroConfig、UserRealm

package henu.soft.xiaosi.config;

import at.pollux.thymeleaf.shiro.dialect.ShiroDialect;
import org.apache.shiro.spring.web.ShiroFilterFactoryBean;
import org.apache.shiro.web.mgt.DefaultWebSecurityManager;
import org.springframework.beans.factory.annotation.Qualifier;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

import java.util.LinkedHashMap;
import java.util.Map;

@Configuration
public class ShiroConfig {
    
    

    /**
     * Shiro认证、授权
     * @param defaultWebSecurityManager
     * @return
     */

    //3.用户
    @Bean
    public ShiroFilterFactoryBean getShiroFilterFactoryBean(@Qualifier("securityManager") DefaultWebSecurityManager defaultWebSecurityManager){
    
    
        ShiroFilterFactoryBean bean = new ShiroFilterFactoryBean();
        //设置安全管理器
        bean.setSecurityManager(defaultWebSecurityManager);

        //添加内置过滤器

        Map<String,String> filterMap = new LinkedHashMap<>();

        //设置未登录认证拦截器
        filterMap.put("/emps","authc");
        filterMap.put("/add","authc");
        filterMap.put("/edit/*","authc");
        filterMap.put("/main.html","authc");
        filterMap.put("/getDepartmentById","authc");
        filterMap.put("/getDepartments/*","authc");


        //设置权限拦截器

        /*
        下面这些权限只能实现单资源单用户(因为Map的Key唯一)，对于单资源多用户需要设置角色)
         */

        filterMap.put("/add","perms[user:root]");



        filterMap.put("/add/*","perms[user:root]");


        filterMap.put("/edit","perms[user:root]");


        filterMap.put("/edit/*","perms[user:root]");

        filterMap.put("/delete/*","perms[user:root]");



        //设置登录的请求,转到自己写的认证页面
        bean.setLoginUrl("/toLogin");

        //未授权访问跳转页面，点击有权限的页面，会自动指定UserRealm的方法
        bean.setUnauthorizedUrl("/limit");

        bean.setFilterChainDefinitionMap(filterMap);


        return bean;
    }


    //2. 管理
    @Bean(name = "securityManager")
    public DefaultWebSecurityManager getDefaultWebSecurityManager(@Qualifier("userRealm") UserRealm userRealm){
    
    
        DefaultWebSecurityManager securityManager = new DefaultWebSecurityManager();
        //关联Realm对象
        securityManager.setRealm(userRealm);
        return securityManager;

    }

    //1. 创建Realm对象，用于处理数据
    @Bean(name = "userRealm")
    public UserRealm userRealm(){
    
    
        return new UserRealm();
    }


    /**
     * Shiro整合Thymeleaf
     *
     * 	配置 ShiroDialect（Shiro 方言） 对象
     *
     */
    @Bean
    public ShiroDialect getShiroDialect(){
    
    
        return new ShiroDialect();
    }
}

package henu.soft.xiaosi.config;

import henu.soft.xiaosi.mapper.UserMapper;
import henu.soft.xiaosi.pojo.User;
import org.apache.shiro.SecurityUtils;
import org.apache.shiro.authc.*;
import org.apache.shiro.authz.AuthorizationInfo;
import org.apache.shiro.authz.SimpleAuthorizationInfo;

import org.apache.shiro.subject.Subject;
import org.springframework.beans.factory.annotation.Autowired;


public class UserRealm extends AuthorizingRealm {
    
    

    @Autowired
    UserMapper userMapper;
    //授权
    @Override
    protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principalCollection) {
    
    
        SimpleAuthorizationInfo info = new SimpleAuthorizationInfo();

        //拿到当前登录的对象
        Subject subject = SecurityUtils.getSubject();
        User currentUser = (User)subject.getPrincipal();
        //System.out.println("debug===>" + currentUser.getLimits());

        //拿出来user表中limits字段
        info.addStringPermission(currentUser.getLimits());
        return info;
    }

    //认证
    @Override
    protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken authenticationToken) throws AuthenticationException {
    
    
//        String username = "scl";

        //刚才的token是全局的，可以在这里取出认证
       UsernamePasswordToken token = (UsernamePasswordToken) authenticationToken;

        User user = userMapper.findLoginUserByName(token.getUsername());

        if(user == null){
    
    
           //用户名认证，用户名不同会自动抛出用户不存在异常
           return null;
       }

        System.out.println("认证方法执行了debug===>" + user.getLimits());
       //密码认证Shiro自己做,如果还需要设置权限授予，需要将user参数传递给SimpleAuthenticationInfo
       return new SimpleAuthenticationInfo(user,user.getPassword(),"");

    }
}

5. RedisConfig
