在STS中配置HSQLDB

标签： eclipse spring hsqldb spring-tool-suite

我正在尝试整理我的第一个Spring项目，并且我使用HSQLDB作为我的内存数据库进行开发和测试。我的集成测试不会运行，因为我似乎无法正确配置数据库。它说我的驱动程序类名有一个问题，但我怀疑它还有更多。 （附带问题：有没有更简单的方法来设置数据库？你如何使用数据库脚本来完成一些工作？）当我运行测试时，这是输出：

这是我的数据库属性文件：

jdbc.driverClassName=org.hsqldb.jdbcDriver
jdbc.url=jdbc:hsqldb:mem:wellness
jdbc.username=sa
jdbc.password=

以下是我的数据库配置方式（当我右键单击hsqldb jar文件并选择RunAs＆gt; Java Application并选择数据库管理器时）。配置看起来我正确匹配我的属性文件： enter image description here

这是我的spring-datasource.xml文件。它应该从属性文件中提取正确的值：

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:p="http://www.springframework.org/schema/p"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns:context="http://www.springframework.org/schema/context"
    xmlns:jdbc="http://www.springframework.org/schema/jdbc"
    xsi:schemaLocation="http://www.springframework.org/schema/beans
        http://www.springframework.org/schema/beans/spring-beans.xsd
        http://www.springframework.org/schema/context
        http://www.springframework.org/schema/context/spring-context.xsd
        http://www.springframework.org/schema/jdbc
        http://www.springframework.org/schema/jdbc/spring-jdbc-3.0.xsd">

    <context:property-placeholder location="classpath:src/main/resources/database-config-testing.properties"/>

    <bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close">
        <property name="driverClassName" value="${jdbc.driverClassName}" />
        <property name="url" value="${jdbc.url}" />
        <property name="username" value="${jdbc.username}" />
        <property name="password" value="${jdbc.password}" />
    </bean>

</beans>

这是我的application-context.xml文件。您可以看到我正在导入数据源xml文件：

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns:context="http://www.springframework.org/schema/context"
    xsi:schemaLocation="http://www.springframework.org/schema/beans
        http://www.springframework.org/schema/beans/spring-beans.xsd
        http://www.springframework.org/schema/context
        http://www.springframework.org/schema/context/spring-context.xsd">

        <context:property-placeholder location="classpath*:META-INF/spring*.properties"/>

        <context:component-scan base-package="com.kylewalker.wellness"/>

        <import resource="spring-datasource.xml"/>

        <bean id="employeeDao" class="com.kylewalker.wellness.data.EmployeeDaoJdbcImpl">
            <constructor-arg ref="jdbcTemplate"/>
        </bean>

        <bean id="employeeService" class="com.kylewalker.wellness.services.EmployeeServiceImpl">
            <constructor-arg ref="employeeDao"/>
        </bean>

        <bean id="jdbcTemplate" class="org.springframework.jdbc.core.namedparam.NamedParameterJdbcTemplate">
            <constructor-arg ref="dataSource"/>
        </bean>


</beans>

这是我的集成测试：

package com.kylewalker.wellness.integrationtests;

import static org.junit.Assert.assertEquals;

import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;

import com.kylewalker.wellness.domain.Employee;
import com.kylewalker.wellness.services.EmployeeService;

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration("/application-config.xml")
public class FindEmployeeIT {

@Autowired
EmployeeService employeeService;

@Test
public void testAddingEmployees() {
    employeeService.addNewEmployee(new Employee("Billy", "Elliot", "bj@home.com"));
    employeeService.addNewEmployee(new Employee("Margaret", "Welsh", "mags@amail.com"));

    int employeesInDatabase = employeeService.getAllEmployees().size();

    assertEquals("There should be two employees in the database.", 2, employeesInDatabase);
}

}
