Question

我在informix版本4.10.6.20151104中使用此属性

    spring.informix.datasource.type=com.zaxxer.hikari.HikariDataSource
 spring.informix.datasource.dataSourceClassName=com.informix.jdbcx.IfxDataSource
      spring.informix.datasource.dataSourceProperties.serverName=CISCO-UCCE-EXP
      spring.informix.datasource.dataSourceProperties.portNumber=1504
     spring.informix.datasource.dbcp2.pool-prepared-statements=true
    spring.informix.datasource.dataSourceProperties.IFXHOST = cisco_ucce_exp_uccx

收到错误

我也尝试过相同的配置 https://docs.oracle.com/cd/E19575-01/821-0185/beanj/index.html 对于IfxIFXHost，我也遇到了同样的问题善意的帮助。 P.S我是Hikari的新手

之前从未使用过Hikari，但是快速测试会显示您应该添加到数据源以获取连接的属性：

使用＆＃34; IFXHOST＆＃34;我得到了例外：

D:\JJTMP>grep IFXHOST p.java
                                                config.addDataSourceProperty("IFXHOST", "420ito");
                                                config.addDataSourceProperty("IfxIFXHOST", "420ito");

D:\JJTMP>java p
[main] INFO com.zaxxer.hikari.HikariDataSource - HikariPool-1 - Starting...
[main] ERROR com.zaxxer.hikari.util.PropertyElf - Property IFXHOST does not exist on target class com.informix.jdbcx.IfxDataSource
Exception in thread "main" java.lang.NullPointerException
        at p.main(p.java:64)

使用＆＃34; IfxIFXHOST＆＃34;工作原理：

D:\JJTMP>grep IFXHOST p.java
                                                //config.addDataSourceProperty("IFXHOST", "420ito");
                                                config.addDataSourceProperty("IfxIFXHOST", "420ito");

D:\JJTMP>javac p.java

Answer 2

所以这对我有用

spring.informix.datasource.type=com.zaxxer.hikari.HikariDataSource
spring.informix.datasource.minimumIdle=10
spring.informix.datasource.maximumPoolSize=30
spring.informix.datasource.idleTimeout=500
spring.informix.datasource.dataSourceClassName=com.informix.jdbcx.IfxDataSource
spring.informix.datasource.dataSourceProperties.databaseName=db_
spring.informix.datasource.dataSourceProperties.serverName=CISCO-UCCE-EXP
#spring.informix.datasource.dataSourceProperties.url = jdbc:informix-sqli://CISCO-UCCE-EXP:1504/db_cra:INFORMIXSERVER=cisco_ucce_exp_uccx; Protocol=onsoctcp; client_locale=en_US.57372; db_locale=en_US.57372
spring.informix.datasource.dataSourceProperties.portNumber=1504
spring.informix.datasource.dbcp2.pool-prepared-statements=true
spring.informix.datasource.dataSourceProperties.LoginTimeout=0
spring.informix.datasource.connectionTimeout=0
spring.informix.datasource.dataSourceProperties.IfxIFXHOST=cisco_ucce_exp_uccx

对于informix，目标类com.informix.jdbcx.IfxDataSource上不存在赋予IFXHOST的Hikari连接池
