1. 当Springboot项目启动时，程序没有遇到报错就停止

-引入

<dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
</dependency>

2. 引入redis的问题

-依赖

       <dependency>
            <groupId>redis.clients</groupId>
            <artifactId>jedis</artifactId>
            <version>3.1.0</version>
        </dependency>

        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-data-redis</artifactId>
        </dependency>

2.1 springboot 整合redis

参考文章实现
https://blog.csdn.net/zhulier1124/article/details/82154937

1/读取yml配置的问题
@ConfigurationProperties 与 @Value公用，因为树的层级较多，无法用prefix全部覆盖

application.yml文件
spring:
   redis:
    host: localhost
    port: 6379
    timeout: 10000
    jedis:
      pool:
        min-idle: 2
        max-idle: 8
        max-active: 10

config.java文件
@Component
@ConfigurationProperties(prefix = "spring.redis",ignoreUnknownFields = true)
@Slf4j
@Data
public class RedisConfig {

    private String host;

    private Integer port;

    @Value("${spring.redis.jedis.pool.max-active}")
    private Integer maxTotal;
   //只能用权限定名获取配置信息
    @Value("${spring.redis.jedis.pool.max-idle}")
    private Integer maxIdle;

    @Value("${spring.redis.jedis.pool.min-idle}")
    private Integer minIdle;

    private Integer timeout;

}

2/ 反序列化报错 Consider defining a bean of type 'xxx' in your configuration问题

3.springboot整合Mybatis

1/使用mybatis generator

依赖

<dependency>
            <groupId>org.mybatis.spring.boot</groupId>
            <artifactId>mybatis-spring-boot-starter</artifactId>
            <version>2.0.1</version>
        </dependency>

        <dependency>
            <groupId>mysql</groupId>
            <artifactId>mysql-connector-java</artifactId>
            <version>5.1.6</version>
        </dependency>

        <dependency>
            <groupId>org.mybatis.generator</groupId>
            <artifactId>mybatis-generator-core</artifactId>
            <version>1.3.2</version>
        </dependency>

        <dependency>
            <groupId>com.alibaba</groupId>
            <artifactId>druid</artifactId>
            <version>1.1.9</version>
        </dependency>

文件标配

2/无法找到mapper问题

对mapper使用@mapper注解

application.yml
mybatis:
  mapper-locations: classpath:mapperss/*.xml
  #注意：一定要对应mapper映射xml文件的所在路径
  type-aliases-package: com.imooc.user.pojo  # 注意：对应实体类的路径

3/cookie注入
java.lang.IllegalArgumentException: An invalid domain [.test.com] was specified for this cookie
