Question

如何在春季3.0中component-scan？对于jar和项目，我使用@Service，@ RTonsity等注释。这是行不通的。当项目中的bean从jar中注入bean时。

在jar文件中

    com.java.spring.support

在项目中

    org.me.project

我的配置是

    <context:annotation-config/>
    <context:component-scan base-package="com.java.spring.support, org.me.project"/>

在Jar文件中

    package com.java.spring.support;

    @Service("CommonService")
    public class CommonService {
    }

在项目中

    package org.me.project;

    @Service(value = "OtherService")
    public class OtherService {
        @Resource(name = "CommonService")
        private CommonService service;
    }

我收到错误

Answer 1

仅限<context:component-scan base-package="com.java.spring.support, org.me.project"> <context:exclude-filter type="annotation" expression="org.springframework.stereotype.Repository"/>使用。

Answer 2

<context:component-scan base-package="org.me.project"/>

您正在对存储库注释使用排除过滤器，将其删除。
