折腾了很久,记录下。

@ConfigurationProperties(prefix = "xx") public class TXMachinesProperties { private List<Map<String, String>> machine1s; public List<Map<String, String>> getMachine1s() { return machine1s; } public void setMachine1s(List<Map<String, String>> machine1s) { this.machine1s = machine1s; } }
注意:
a.这里prefix写到接收对象的前一级即可;
b.这里的变量名必须要与配置的名称一致,才可自动接收。
这里其实可与上面的配置类写在一起,但是一个类就是做一件事情,就做了隔离。
@Configuration @EnableConfigurationProperties({TXMachinesProperties.class}) public class TXMachinesConfig { }
采用下面的方式即可。这里注意,由于使用这个yml的注解是属于SpringBoot的框架内进行的,因此这个属性注入只能在标有Spring的注解的类的范围内使用,不能在普通类使用。
@Autowired private TXWorkShopAlarmProperties txWorkShopAlarmProperties;
可以解决了~
yml里的list配置(以 - 开头的行表示构成一个数组:):
weixin: configs: - schId: 111 appId: 11111 appSecret: 11111 templateId: 111111 - schId: 2222 appId: 222222 appSecret: 2222222 templateId: 2222222
导入jar包
<dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-configuration-processor</artifactId> <version>2.2.1.RELEASE</version> </dependency>
写一个微信配置的实体类,将配置文件中配置的每一个属性的值,映射到这个实体类中
import lombok.Data; import org.springframework.boot.context.properties.ConfigurationProperties; import org.springframework.stereotype.Component; import java.util.List; @Component @Data @ConfigurationProperties(prefix = "weixin") public class WxConfig { private List<Config> configs; @Data public static class Config { private Integer schId; private String appId; private String appSecret; private String templateId; } }
1.注入该实体类
@Autowired private WxConfig wxConfig;
2.解析,我这里是将其转为学校id为key的map,方便我后面使用,按照自己想要的读取就好了JSON.toJSONString(wxConfig)
public Map<Integer,Map> getWeiXinConfig(){ JSONObject o = JSON.parseObject(JSON.toJSONString(wxConfig)); JSONArray jsonArray = o.getJSONArray("configs"); Map<Integer,Map> map = new HashMap<>(); if (jsonArray.size() != 0) { for (int j = 0; j < jsonArray.size(); j++) { Map map2 = new HashMap(); JSONObject o1 = jsonArray.getJSONObject(j); String appId = o1.getString("appId"); String appSecret = o1.getString("appSecret"); Integer schId = o1.getIntValue("schId"); String templateId = o1.getString("templateId"); map2.put("appId", appId); map2.put("appSecret", appSecret); map2.put("schId", schId); map2.put("templateId", templateId); map.put(schId,map2); } } return map; }
调用方法getWeiXinConfig(),输出map的输出结果:
