我不能在@Configuration文件@Autowire字段

我的项目是Java配置和XML配置的混合。我不能在@Configuration文件@Autowire字段

请看看这些文件。我不能自动装配private DataSource dataSource;

@Configuration 
@EnableWebSecurity 
public class SecurityConfig extends WebSecurityConfigurerAdapter{ 


    @Autowired 
    private DataSource dataSource; 

    public void setDataSource(DataSource dataSource) { 
     this.dataSource = dataSource; 
    } 

    @Autowired 
    public void configureGlobal(AuthenticationManagerBuilder auth) throws Exception { 
     auth 
       .inMemoryAuthentication() 
       .withUser("user").password("password").roles("USER"); 
    }

和

<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"

我在应用程序启动时出现错误。这些是日志详细信息：

请在出现错误的地方以及何时何处添加更多信息＃ –

我无法autowiere私有DataSource dataSource; – Przemek

尝试arseniyandru的建议，我认为这可能是解决方案 –

为什么不在编程类中写入Bean的定义？你可以在里面配置所有的配置。您不需要applicationContext.xml和Configuration类。

我想同时具有xml和java配置。这不是我的问题的答案。 – Przemek

看起来像xml中的数据源的Bean定义是与配置文件不同的类型。数据源bean的类型是'org.springframework.jdbc.datasource.DriverManagerDataSource'，你的@autowired数据源的类型是'javax.sql.DataSource'，这就是为什么Spring不能自动装载它的原因，因为它可以'找到相同类型的Bean。 – Daniel

DriverManagerDataSource是一个javax.sql.DataSource，所以我不认为这是问题（除非有多个DataSource定义的过程） –

找不到符合条件的[javax.sql.DataSource]类型的限定bean：期望至少有1个bean - 看起来像您的DataSource是不同的类型。配置和xml中的dataSource类型之间是否存在不匹配？ org.springframework.jdbc.datasource.DriverManagerDataSource和javax.sql.DataSource。

我不认为只是为了测试的缘故，我删除了这个私有的DataSource数据源并用私有JdbcTemplate jdbcTemplate替换它。只是为了测试它是否工作（我在我的xml文件中定义了这个bean），这会导致类似的问题。 – Przemek

TL; DR - 修复您的导入是与您的bean定义为你自动装配Autowired对象。

是否有可能您的DataSource对象的导入与您的spring xml中的bean定义不同？

在异常，上面清清楚楚地写着：

“式的没有合格豆[的javax.sql.DataSource]发现依赖性：预计将有至少1 Bean上有资格作为自动装配候选人这种依赖性。“

凡在你的Spring的XML你的bean定义，你必须：

<bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource">

所以，尽量解决您的import语句使用同一个作为你的bean定义。

我做到了，但没有帮助。 – Przemek

我认为你需要首先在Java配置中包含你的xml配置。

@ImportResource("classpath:yourconfig.xml")

此外，setDataSource似乎是多余的，并且自动布线字段从不使用 –

@ImportResource（“classpath：webstore \\ src \\ main \\ webapp \\ WEB-INF \\ spring \\ webcontext \\ DispatcherServlet-context.xml”）我把这个，但它没有帮助。我还更改了导入定义以导入org.springframework.jdbc.datasource.DriverManagerDataSource。那么它说这样的XML文件剂量存在。 – Przemek

该文件不在类路径中，并且您不应该在java中使用\（即使您使用的是windows） –

我不能在@Configuration文件@Autowire字段
