java.lang.IllegalArgumentException：沒有指定SqlMapClient

我想要訪問iBatis的JUnit DAO。問題是iBatis無法讀取SqlMapClient，儘管我在applicationContext.xml中指定了它。所以我試圖設置它的完整路徑，但我仍然遇到錯誤。java.lang.IllegalArgumentException：沒有指定SqlMapClient

的applicationContext.xml

<!-- Sql Map Client --> 
<bean id="sqlMapClient" class="org.springframework.orm.ibatis.SqlMapClientFactoryBean"> 
    <property name="configLocation" value="file:C:/workspace/MyProject/WebContent/WEB-INF/sqlMapConfig.xml" /> 
    <property name="dataSource" ref="dataSource"/> 
</bean>

的JUnit代碼

@RunWith(SpringJUnit4ClassRunner.class) 
@ContextConfiguration(
locations={ 
    "file:C:/workspace/MyProject/WebContent/WEB-INF/sqlMapConfig.xml", 
    "file:C:/workspace/MyProject/WebContent/WEB-INF/applicationContext.xml", 
    "file:C:/workspace/MyProject/WebContent/WEB-INF/dataSource.xml", 
} 
) 

// This doesn't work 
//locations={ 
//"classpath:/WEB-INF/sqlMapConfig.xml", 
//"classpath:/WEB-INF/applicationContext.xml", 
//"classpath:/WEB-INF/dataSource.xml", 
//} 

public class ProductDaoTest { 
    /** 
    * Run the List<Product> getProductList(Product) method test. 
    * 
    * @throws Exception 
    * 
    * @generatedBy CodePro at 7/1/13 10:55 AM 
    */ 
    @Test 
    public void testGetProductList() 
     throws Exception { 
     ProductDao fixture = new ProductDao(); 
     Product product = new Product(); 

     List<Product> result = fixture.getProductList(product); 
     assertNotNull(result); 
    } 
}

我得到這個錯誤

注入你的'ProductDao'，而不是自己創建新實例。 –

我的源代碼使用'@ Autowired'來創建ProductDao。我試圖在UnitTest中使用'@ Autowired'，但它生成NullPointerException，productDao無法初始化。 – Emerald214

當你嘗試注入道什麼異常，你會得到什麼？ –

我猜的錯誤也許在

ProductDao fixture = new ProductDao();

嘗試將其更改爲

WebApplicationContext wac = WebApplicationContextUtils. 
        getRequiredWebApplicationContext(config.getServletContext()); 

ProductDao fixture = (ProductDao) wac.getBean("ProductDao");

什麼是'config'？我沒有它。 – Emerald214

您需要通過傳遞ServletContext或Spring來獲取DAO –
