我设置 application.properties 如下

---

spring.datasource.hikari.driver-class-name=com.microsoft.sqlserver.jdbc.SQLServerDriver
spring.datasource.url=jdbc:sqlserver://localhost:1433;databaseName=Spring_Boot;integratedSecurity=true;encrypt=true;trustServerCertificate=true
spring.datasource.hikari.username=aaa
spring.datasource.hikari.password=1234
spring.jpa.show-sql=true
spring.jpa.properties.hibernate.format_sql=true
spring.jpa.properties.hibernate.dialect=org.hibernate.dialect.SQLServer2019Dialect
spring.jpa.hibernate.ddl-auto=update
mybatis.configuration.map-underscore-to-camel-case=true



spring.jpa.defer-datasource-initialization=true

---

我检查了build.gradle

---

plugins {
    id 'java'
    id 'org.springframework.boot' version '3.2.2-SNAPSHOT'
    id 'io.spring.dependency-management' version '1.1.4'
}

group = 'com.example'
version = '0.0.1-SNAPSHOT'

java {
    sourceCompatibility = '17'
}

configurations {
    compileOnly {
        extendsFrom annotationProcessor
    }
}

repositories {
    mavenCentral()
    maven { url 'https://repo.spring.io/milestone' }
    maven { url 'https://repo.spring.io/snapshot' }
}

dependencies {
    implementation 'org.springframework.boot:spring-boot-starter-data-jpa'
    implementation 'org.springframework.boot:spring-boot-starter-thymeleaf'
    implementation 'org.springframework.boot:spring-boot-starter-web'
    implementation 'org.mybatis.spring.boot:mybatis-spring-boot-starter:3.0.3'
    compileOnly 'org.projectlombok:lombok'
    developmentOnly 'org.springframework.boot:spring-boot-devtools'
    runtimeOnly 'com.microsoft.sqlserver:mssql-jdbc'
    annotationProcessor 'org.springframework.boot:spring-boot-configuration-processor'
    annotationProcessor 'org.projectlombok:lombok'
    testImplementation 'org.springframework.boot:spring-boot-starter-test'
    testImplementation 'org.mybatis.spring.boot:mybatis-spring-boot-starter-test:3.0.3'

    
}

tasks.named('test') {
    useJUnitPlatform()
}

它们看起来没有问题，Service、Controller、Mapper 中的注释也没有问题。

你能帮我吗？

Answer 1

您的数据源属性命名不正确。不能有

hikari

-标记

spring.datasource.driver-class-name=com.microsoft.sqlserver.jdbc.SQLServerDriver
spring.datasource.url=jdbc:sqlserver://localhost:1433;databaseName=Spring_Boot;integratedSecurity=true;encrypt=true;trustServerCertificate=true
spring.datasource.username=aaa
