Question

我正在使用Spring Boot应用程序： https://github.com/kswr/wallets-api（开发分支）它连接到本地Postgres实例并可以执行get操作。但是，当我在Tomcat实例上放置.war时，出现以下错误

Caused by: org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'org.springframework.boot.autoconfigure.orm.jpa.                       
HibernateJpaConfiguration': Unsatisfied dependency expressed through constructor parameter 0; 
nested exception is org.springframework.beans.factory.BeanCreationException: Error  creating bean with name 'dataSource' defined in class path resource [org/springframework/boot/autoconfigure/jdbc/DataSourceConfiguration$Hikari.class]: Bean instantiation via factory method failed; 
nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [com.zaxxer.hikari.HikariDataSource]: Factory method       'dataSource' threw exception; 
nested exception is org.springframework.boot.autoconfigure.jdbc.DataSourceProperties$DataSourceBeanCreationException: Failed to determine a suitable driver class

我不确定是Spring Boot还是Tomcat问题，我尝试为Tomcat安装postgres驱动程序，并在$CATALINA_HOME/conf/Catalina/localhost/wallets-api-develop.xml中进行如下配置，但似乎没有任何改变

<Context>
<Resource name="jdbc/postgres" scope="Shareable" type="javax.sql.DataSource"/>
<ResourceParams name="jdbc/postgres">
    <parameter>
        <name>validationQuery</name>
        <value>select version();</value>
    </parameter>

    <parameter>

        <value>kswr</value>
    </parameter>
    <parameter>
        <name>maxIdle</name>
        <value>2</value>
    </parameter>
</ResourceParams> 
</Context>

这实际上是application.properties的问题；显然-D参数在运行时有效，而我的Jenkins管道仅在编译时提供它们，因此Tomcat无法使用application-staging.properties（包含正确的数据源配置）。

使用Postgresql进行Spring Boot的Tomcat配置
