Question

Env：Eclipse + sts

我新建了一个Spring Starter项目，选择JDBC API，MS SQL Server驱动程序，Spring Web Starter。

第一次创建时，会出现如下错误：

Multiple annotations found at this line: - Plugin execution not covered by lifecycle configuration: org.apache.maven.plugins:maven-resources-plugin:3.1.0:testResources (execution: default-testResources, phase: process-test-resources) - Plugin execution not covered by lifecycle configuration: org.apache.maven.plugins:maven-resources-plugin:3.1.0:resources (execution: default-resources, phase: process-resources)

我忽略了它。我在pom文件中添加了资源，

    <resources>
    <resource>
        <directory>src/main/java</directory>
        <includes>
            <include>**/*.yml</include>
        </includes>
        <filtering>false</filtering>
    </resource>
    <resource>
        <directory>src/main/resources</directory>
        <includes>
            <include>**/*.yml</include>
        </includes>
        <filtering>false</filtering>
    </resource>
</resources>

然后我在src / main / resources / application.yml中添加SQL Server内容 spring: datasource: driverClassName: com.microsoft.sqlserver.jdbc.SQLServerDriver password: sly url: jdbc:sqlserver://localhost:1433;DatabaseName=msdb username: sa

但是我运行@SpringBootApplication，它提供信息

Description:
Failed to configure a DataSource: 'url' attribute is not specified and no embedded datasource could be configured.
Reason: Failed to determine a suitable driver class

我尝试过application.properties，它也不起作用。

spring.datasource.url=jdbc:sqlserver://localhost:1433;DatabaseName=msdb
spring.datasource.driver-class-name=com.microsoft.sqlserver.jdbc.SQLServerDriver
spring.datasource.username=sa
spring.datasource.password=sly

<include>**/*.properties</include>

然后我尝试另一种方法，即创建文件DatasourceConfig.java并对其进行编码

package com.ycr;

import javax.sql.DataSource;

import org.springframework.boot.jdbc.DataSourceBuilder;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

@Configuration
public class DatasourceConfig {
    @Bean
    public DataSource datasource() {
        return DataSourceBuilder.create().driverClassName("com.microsoft.sqlserver.jdbc.SQLServerDriver")
                .url("jdbc:sqlserver://localhost:1433;DatabaseName=msdb").username("sa").password("sly").build();
    }
}

，它起作用。我不知道为什么它无法读取我的yml文件？（将yml更改为属性不起作用。）

我想知道为什么它无法读取我的yml文件？（将yml更改为属性不起作用。）

无法读取application.yml文件
