Java 弹簧外形异常

我试图弄清楚如何使用Spring概要文件进行测试。我想我做的每一件事都是根据spring文档。最后我得到了我无法解释的结果，这里是我的程序列表：

以下是主要配置：

package com.test.profiles;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.Profile;

import java.util.HashMap;
import java.util.Map;

@Configuration
@ComponentScan("com.test.profiles")
public class MainConfig {

@Autowired
private String helloMsg;

@Autowired
private Map<String,String> profileDependentProps;

@Bean
@Profile("default")
public String helloMsg() {
    return "Hello default";
}

@Bean
@Profile("default")
public Map<String,String> profileDependentProps() {
    Map<String,String> props = new HashMap<>();
    props.put("1", "default");
    props.put("2", "default");
    props.put("3", "default");
    return props;
}
}

这条线是怎么回事helloMsg=Hello dev

我的映射在哪里？

默认情况下，当Spring遇到类型为

map

的自动布线字段时，它将注入特定

[type]

的bean映射。在您的情况下，

字符串

。您将无法获取已配置的映射

请参阅：

您基本上遇到了一个角落案例，因为您有一个以字符串为键的地图。要获取bean，您必须在

@Autowired

旁边放置一个

@限定符（“profileDependentProps”）

，或者使用

@Resource（“profileDependentProps”）

而不是

@Autowired

package com.test.profiles;

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.Profile;

import java.util.HashMap;
import java.util.Map;

@Configuration
@Profile("dev")
public class TestConfig {

@Bean
public String helloMsg() {
    return "Hello dev";
}

@Bean
public Map<String,String> profileDependentProps() {
    Map<String,String> props = new HashMap<>();
    props.put("1", "dev");
    props.put("2", "dev");
    props.put("3", "dev");
    return props;
}
}

package com.test.profiles;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.test.context.ActiveProfiles;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.testng.AbstractTestNGSpringContextTests;
import org.testng.annotations.Test;

import java.util.Map;

@ContextConfiguration(classes = MainConfig.class)
@ActiveProfiles("dev")
public class ProfileTester extends AbstractTestNGSpringContextTests {

@Autowired
private String string;

@Autowired
private Map<String,String> profileDependentProps;

@Test
public void profileTest() {
    System.out.println("TEST: "+string);
    for(Map.Entry<String,String> entry : profileDependentProps.entrySet()) {
        System.out.println(entry.getKey() + "=" + entry.getValue());
    }
}
}
