[英]Tomcat configuration for Spring Boot with Postgresql
我有一個正在運行的Spring Boot應用程序: https : //github.com/kswr/wallets-api (開發分支),它連接到本地Postgres實例並可以執行get操作。 但是,當我在Tomcat實例上放置.war時,出現以下錯誤
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
我不確定這是Spring Boot還是Tomcat問題,我嘗試為Tomcat安裝postgres驅動程序,並在$CATALINA_HOME/conf/Catalina/localhost/wallets-api-develop.xml
如下配置,但似乎沒有改變任何東西
<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>
<name>url</name>
<value>jdbc:postgresql://localhost:5432/wallets</value>
</parameter>
<parameter>
<name>password</name>
<value>admin</value>
</parameter>
<parameter>
<name>maxActive</name>
<value>4</value>
</parameter>
<parameter>
<name>maxWait</name>
<value>5000</value>
</parameter>
<parameter>
<name>driverClassName</name>
<value>org.postgresql.Driver</value>
</parameter>
<parameter>
<name>username</name>
<value>kswr</value>
</parameter>
<parameter>
<name>maxIdle</name>
<value>2</value>
</parameter>
</ResourceParams>
</Context>
實際上這是application.properties的問題; 顯然-D參數在運行時有效,而我的Jenkins管道僅在編譯時提供它們,因此Tomcat無法使用application-staging.properties(包含正確的數據源配置)。
