Caused by: java.lang.IllegalArgumentException: Property ‘sqlSessionFactory‘ or ‘sqlSessionTemplate‘

Springboot项目引入mybatis后启动报错：

Caused by: java.lang.IllegalArgumentException: Property 'sqlSessionFactory' or 'sqlSessionTemplate' are required

1. 确保启动类没有排除数据库自动配置

错误配置如下：

下面配置中，使用exclude = {DataSourceAutoConfiguration.class}排除了数据库自动配置，因此启动会报错。

@SpringBootApplication(exclude = {DataSourceAutoConfiguration.class})
public class IstioAdminApplication {
    public static void main(String[] args) {
        SpringApplication.run(IstioAdminApplication.class, args);
    }
}

正确配置：

@SpringBootApplication()
public class IstioAdminApplication {
    public static void main(String[] args) {
        SpringApplication.run(IstioAdminApplication.class, args);
    }
}

2. 确保application.yml配置了数据库连接配置

spring:
  datasource:
    username: root # change this
    password: root # change this
    url: jdbc:mysql://10.10.1.10:3306/servicemesh_platform?useUnicode=true&characterEncoding=utf-8&serverTimezone=UTC # change this
    driver-class-name: com.mysql.cj.jdbc.Driver
