将spring上下文从xml重写为java

我正在将我的Spring上下文从XML重写为Java类，但下面这个bean我不知道。有人能帮我吗？我用的是弹簧靴

<bean class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
    <property name="systemPropertiesModeName" value="SYSTEM_PROPERTIES_MODE_OVERRIDE" />
    <property name="order" value="10"/>
    <property name="ignoreUnresolvablePlaceholders" value="true" />
    <property 
              name="properties" ref="externalConfigProperties">
    </property>
</bean>

大致如下：

@Bean
@Autowired
public PropertyPlaceholderConfigurer properties(Properties externalProperties) {
    PropertyPlaceholderConfigurer propertiesBean = new PropertyPlaceholderConfigurer();
    propertiesBean.setIgnoreUnresolvablePlaceholders(true);
    propertiesBean.setSystemPropertiesModeName("SYSTEM_PROPERTIES_MODE_OVERRIDE");
    propertiesBean.setOrder("10");
    propertiesBean.setProperties(externalProperties);
    return propertiesBean;
}

按照这些思路：

@Bean
@Autowired
public PropertyPlaceholderConfigurer properties(Properties externalProperties) {
    PropertyPlaceholderConfigurer propertiesBean = new PropertyPlaceholderConfigurer();
    propertiesBean.setIgnoreUnresolvablePlaceholders(true);
    propertiesBean.setSystemPropertiesModeName("SYSTEM_PROPERTIES_MODE_OVERRIDE");
    propertiesBean.setOrder("10");
    propertiesBean.setProperties(externalProperties);
    return propertiesBean;
}

按照这些思路：

@Bean
@Autowired
public PropertyPlaceholderConfigurer properties(Properties externalProperties) {
    PropertyPlaceholderConfigurer propertiesBean = new PropertyPlaceholderConfigurer();
    propertiesBean.setIgnoreUnresolvablePlaceholders(true);
    propertiesBean.setSystemPropertiesModeName("SYSTEM_PROPERTIES_MODE_OVERRIDE");
    propertiesBean.setOrder("10");
    propertiesBean.setProperties(externalProperties);
    return propertiesBean;
}

按照这些思路：

@Bean
@Autowired
public PropertyPlaceholderConfigurer properties(Properties externalProperties) {
    PropertyPlaceholderConfigurer propertiesBean = new PropertyPlaceholderConfigurer();
    propertiesBean.setIgnoreUnresolvablePlaceholders(true);
    propertiesBean.setSystemPropertiesModeName("SYSTEM_PROPERTIES_MODE_OVERRIDE");
    propertiesBean.setOrder("10");
    propertiesBean.setProperties(externalProperties);
    return propertiesBean;
}

试试这个：

@Configuration
public class Config {

    @Autowired Properties externalConfigProperties;

    @Bean
    PropertyPlaceholderConfigurer configurer(){
        PropertyPlaceholderConfigurer configurer = new PropertyPlaceholderConfigurer();
        configurer.setSystemPropertiesModeName("SYSTEM_PROPERTIES_MODE_OVERRIDE");
        configurer.setOrder(10);
        configurer.setIgnoreUnresolvablePlaceholders(true);
        configurer.setProperties(externalConfigProperties);
        return configurer;
    }

}

试试这个：

@Configuration
public class Config {

    @Autowired Properties externalConfigProperties;

    @Bean
    PropertyPlaceholderConfigurer configurer(){
        PropertyPlaceholderConfigurer configurer = new PropertyPlaceholderConfigurer();
        configurer.setSystemPropertiesModeName("SYSTEM_PROPERTIES_MODE_OVERRIDE");
        configurer.setOrder(10);
        configurer.setIgnoreUnresolvablePlaceholders(true);
        configurer.setProperties(externalConfigProperties);
        return configurer;
    }

}

试试这个：

@Configuration
public class Config {

    @Autowired Properties externalConfigProperties;

    @Bean
    PropertyPlaceholderConfigurer configurer(){
        PropertyPlaceholderConfigurer configurer = new PropertyPlaceholderConfigurer();
        configurer.setSystemPropertiesModeName("SYSTEM_PROPERTIES_MODE_OVERRIDE");
        configurer.setOrder(10);
        configurer.setIgnoreUnresolvablePlaceholders(true);
        configurer.setProperties(externalConfigProperties);
        return configurer;
    }

}

试试这个：

@Configuration
public class Config {

    @Autowired Properties externalConfigProperties;

    @Bean
    PropertyPlaceholderConfigurer configurer(){
        PropertyPlaceholderConfigurer configurer = new PropertyPlaceholderConfigurer();
        configurer.setSystemPropertiesModeName("SYSTEM_PROPERTIES_MODE_OVERRIDE");
        configurer.setOrder(10);
        configurer.setIgnoreUnresolvablePlaceholders(true);
        configurer.setProperties(externalConfigProperties);
        return configurer;
    }

}

对于较新版本的Spring，建议使用

PropertySourcesPlaceholderConfigurer

而不是

PropertyPlaceholderConfigurer

。定义

BeanFactoryPostProcessor

时，应将其注册为中提到的

公共静态

@Bean

方法

要加载属性，请添加一个指向属性文件位置的

@PropertySource

@Configuration
@PropertySource("path/to/your/config.properties")
public class Config {

    @Bean
    public static PropertySourcePlaceholderConfigurer configurer(){
        PropertySourcePlaceholderConfigurer configurer = new PropertySourcePlaceholderConfigurer();            
        configurer.setOrder(10);
        configurer.setIgnoreUnresolvablePlaceholders(true);         
        return configurer;
    }   
}

是的-这个：）我最初把bean上的属性误认为是属性的一部分。当我编辑我的答案时，这个答案突然出现了。是的-这个：）我最初把bean上的属性误认为是属性的一部分。当我编辑我的答案时，这个答案突然出现了。是的-这个：）我最初把bean上的属性误认为是属性的一部分。当我编辑我的答案时，这个答案突然出现了。是的-这个：）我最初把bean上的属性误认为是属性的一部分。当我编辑我的答案时，这个答案突然出现了。
