不用记录，作者的文档太好了，没必要摘抄，直接阅读作者的文档即可，关键是后期的具体实现
一、常用依赖
org.springframework.boot
spring-boot-starter-web
org.projectlombok
lombok
org.springframework.boot
spring-boot-devtools
runtime
true
org.webjars
bootstrap
4.4.1
org.webjars
jquery
3.4.1
org.webjars
webjars-locator
0.36
org.apache.commons
commons-lang3
二、各种配置
1. mysql
mysql
mysql-connector-java
spring:
datasource:
url: jdbc:mysql://localhost:3306/web-test?serverTimezone=UTC&useUnicode=true&characterEncoding=utf-8&useSSL=true
username: root
password: root
driver-class-name: com.mysql.cj.jdbc.Driver2. jpa
org.springframework.boot
spring-boot-starter-data-jpa
spring:
jpa:
properties:
hibernate:
hbm2ddl.auto: update
dialect: org.hibernate.dialect.MySQL5InnoDBDialect
show-sql: true3. thymeleaf
org.springframework.boot
spring-boot-starter-thymeleaf
spring:
thymeleaf:
cache: false
check-template: true
check-template-location: true
servlet.content-type: text/html
encoding: utf-8
mode: HTML
prefix: classpath:/templates/
suffix: .html4. spring-boot log配置
logging:
file:
path: /user/local/log
level:
com.example.demo: INFO
org.springframework: DEBUG
org.hibernate: Error
org.springframework.boot.autoconfigure: ERROR # 当出现error时显示报告5. springboot-redis配置
org.springframework.boot
spring-boot-starter-data-redis
org.apache.commons
commons-pool2
- 使用jedis：Jedis在实现上是直接连接的redis server，如果在多线程环境下是非线程安全的，这个时候只有使用连接池，为每个Jedis实例增加物理连接
- 使用Lettuce：Lettuce的连接是基于Netty的，连接实例（StatefulRedisConnection）可以在多个线程间并发访问，应为StatefulRedisConnection是线程安全的，所以一个连接实例
spring:
redis:
database: 0 # redis索引默认为0
host: localhost
port: 6379
password: # 默认为空
lettuce:
pool:
max-active: 8
max-idle: 8
max-wait: -1ms
min-idle: 0@Configuration
@ConditionalOnClass(RedisOperations.class)
@EnableConfigurationProperties(RedisProperties.class)
@Import({ LettuceConnectionConfiguration.class, JedisConnectionConfiguration.class })
public class RedisAutoConfiguration {
@Bean
@ConditionalOnMissingBean(name = "redisTemplate")
public RedisTemplate redisTemplate(
RedisConnectionFactory redisConnectionFactory) throws UnknownHostException {
RedisTemplate template = new RedisTemplate<>();
template.setConnectionFactory(redisConnectionFactory);
return template;
}
@Bean
@ConditionalOnMissingBean
public StringRedisTemplate stringRedisTemplate(
RedisConnectionFactory redisConnectionFactory) throws UnknownHostException {
StringRedisTemplate template = new StringRedisTemplate();
template.setConnectionFactory(redisConnectionFactory);
return template;
}
}
- 其中 StringRedisTemplate 是 RedisTemplate 的子类，两个的方法基本一致，不同之处主要体现在操作的数据类型不同
- RedisTemplate 中的两个泛型都是 Object ，意味者存储的 key 和 value 都可以是一个对象
- StringRedisTemplate 的 两个泛型都是 String ，意味者 StringRedisTemplate 的 key 和 value 都只能是字符串
- 共有方法，例如：.opsForValue().set() .opsForValue.get()
Redis 数据类型
- String
- Hash
- List
- Set
- Zset
特别注意：void set(K key, V value, long timeout, TimeUnit unit); 有失效时间一说
6. Redis-Session
org.springframework.session
spring-session-data-redis
@Configuration
@EnableRedisHttpSession(maxInactiveIntervalInSeconds = 86400*30)
public class SessionConfig {
}7. mybatis
org.mybatis.spring.boot
mybatis-spring-boot-starter
2.1.1
#{}与${}
// This example creates a prepared statement, something like select * from teacher where name = ?; @Select("Select * from teacher where name = #{name}") Teacher selectTeachForGivenName(@Param("name") String name); // This example creates n inlined statement, something like select * from teacher where name = 'someName'; @Select("Select * from teacher where name = '${name}'") Teacher selectTeachForGivenName(@Param("name") String name);
两种方式： (指定别名：
mybatis:
type-aliases-package: model注解版与配置版
1) 注解版
例如：
@Select("select * from user")
@Results({
@Result(property = "email",column = "email"),
@Result(property = "username",column = "username"),
@Result(property = "pwd",column = "pwd")
})
List getAll(); 2) 配置版
mybatis:
config-location: classpath:mybatis/mybatis-config.xml
mapper-locations: classpath:mybatis/mapper/*.xmlmybatis-config.xml
UserMapper.xml
id, email, username, pwd
INSERT INTO
user
(email,username,pwd)
VALUES
(#{email}, #{username}, #{pwd})
UPDATE
users
SET
email= #{email},
username= #{username},
pwd= #{pwd},
WHERE
id = #{id}
DELETE FROM
user
WHERE
id =#{id}
mybatis多数据源：连接两个数据库
其中配置关键： @Primary指定主数据源
- DataSourceProperties
- DataSource
- SqlSessionFactory
- DataSourceTransactionManager
- SqlSessionTemplate
@Configuration
@MapperScan(basePackages = "com.example.demo.mapper.test1",sqlSessionTemplateRef = "ds1SqlSessionTemplateRef")
public class MybatisDS1Config {
// 主数据源配置 ds1数据源
@Primary
@Bean(name = "ds1DataSourceProperties")
@ConfigurationProperties(prefix = "spring.datasource.ds1")
public DataSourceProperties ds1DataSourceProperties() {
return new DataSourceProperties();
}
// 主数据源 ds1数据源
@Primary
@Bean(name = "ds1DataSource")
public DataSource ds1DataSource(@Qualifier("ds1DataSourceProperties") DataSourceProperties dataSourceProperties) {
return dataSourceProperties.initializeDataSourceBuilder().build();
}
// 主数据源 ds1数据源
@Primary
@Bean("ds1SqlSessionFactory")
public SqlSessionFactory ds1SqlSessionFactory(@Qualifier("ds1DataSource") DataSource dataSource) throws Exception {
SqlSessionFactoryBean sqlSessionFactory = new SqlSessionFactoryBean();
sqlSessionFactory.setDataSource(dataSource);
sqlSessionFactory.setMapperLocations(new PathMatchingResourcePatternResolver().
getResources("classpath*:com/example/demo/mapper/**/*.xml"));
return sqlSessionFactory.getObject();
}
@Primary
@Bean(name = "ds1TransactionManager")
public DataSourceTransactionManager ds1TransactionManager(@Qualifier("ds1DataSource") DataSource dataSource) {
return new DataSourceTransactionManager(dataSource);
}
@Primary
@Bean(name = "ds1SqlSessionTemplate")
public SqlSessionTemplate ds1SqlSessionTemplate(@Qualifier("ds1SqlSessionFactory") SqlSessionFactory sqlSessionFactory) {
return new SqlSessionTemplate(sqlSessionFactory);
}
}8. RabbitMQ
win10安装：Erlang与RabbitMQ安装时版本需要对应
了解：
- RabbitMQ：消息队列，实现应用程序的异步与解耦，同时起到消息缓冲和消息分发
- 生产者与消费者
- AMQP：Advanced Message Queuing Protocol 高级消息队列协议
- 发消息者、队列、收消息者
- 虚拟主机：一个虚拟主机持有一组交换机、队列和绑定，每一个 RabbitMQ 服务器都有一个默认的虚拟主机“/”
- 交换机：功能主要时接收消息并且转发到绑定的队列，不做存储，如果没有 Queue bind 到 Exchange 的话，它会直接丢弃掉 Producer 发送过来的消息
- 绑定：也就是交换机需要和队列相绑定
- 交换机的类型：Direc类型行为是”先匹配, 再投送”. 即在绑定时设定一个 routing_key, 消息的routing_key 匹配时, 才会被交换器投送到绑定的队列中去；Topic按照规则转发消息；Headers设置 header attribute 参数类型的交换机；Fanout转发消息到所有绑定队列
依赖：
org.springframework.boot

password: guest9. 定时任务：SchedulerTask
org.springframework.boot
spring-boot-starter
cron="*/6 * * * * ?" ============== fixedRate = 6000 每隔6s打印
10. 邮件服务
org.springframework.boot
spring-boot-starter-mail

11. mongodb 默认没有密码
org.springframework.boot
spring-boot-starter-data-mongodb
2.2.5.RELEASE
spring:
data:
mongodb:
uri: mongodb使用时要先创建集合(数据库)
12. shiro
摘抄自"纯洁的微笑的springboot笔记"
shiro功能： 较spring security更加简洁
- 验证用户身份
- 用户访问权限控制
- 在非 Web 或 EJB 容器的环境下可以任意使用 Session API
- 可以响应认证、访问控制，或者 Session 生命周期中发生的事件
- 可将一个或以上用户安全数据源数据组合成一个复合的用户 “view”(视图)
- 支持单点登录(SSO)功能
- 支持提供“Remember Me”服务，获取用户关联信息而无需登录
shiro架构主要理念：
13. upload
spring:
servlet:
multipart:14. FastDFS 文件分布式文件系统
1) win10 开启tracker服务
docker run -dti --network=host --name tracker -v /var/fdfs/tracker:/var/fdfs delron/fastdfs tracker
2) storage服务
docker run -dti --network=host --name storage -e TRACKER_SERVER=192.168.0.104:22122 -v /var/fdfs/storage:/var/fdfs delron/fastdfs storage
14. actuator

16. docker-nginx-mysql
nginx win10：https://blog.csdn.net/u010417597/article/details/85316714 使用cmd(获取管理员权限)
三、常用工具类
1. MD5Util
public class MD5Util {
public static String encrypt(String dataStr) {
try {
MessageDigest m = MessageDigest.getInstance("MD5");
m.update(dataStr.getBytes("UTF8"));
byte s[] = m.digest();
String result = "";
for (int i = 0; i < s.length; i++) {
result += Integer.toHexString((0x000000FF & s[i]) | 0xFFFFFF00)
.substring(6);
}
return result;
} catch (Exception e) {
e.printStackTrace();
}
return "";
}
}2. userID加密类：Des3EncryptionUtil
3. Base64编码类： Base64
4. 资源过滤配置类：SecurityConfig
