springboot reads map and list type configuration parameters in .properties configuration file
A set of configuration parameters are stored in the file, namely map type and list type, and the configuration parameters are read through the test method.
1. Configuration file
#map The first method=zhangsan =man =11 =xxxxxxxx #map The second way[name]=zhangsan [sex]=man [age]=11 [url]=xxxxxxxx #list The first way[0]=apple0 [1]=apple1 [2]=apple2 #list The second way=apple0,apple1,apple2
2. Inject configuration information
@Configuration @ConfigurationProperties(prefix = "data") //If there is only one main configuration class file, @PropertySource can be ignored@PropertySource("classpath:") public class PersonConfig { /** * * The map name here needs to be consistent with the parameters in it */ private Map<String, String> person = new HashMap<>(); /** * * The list name here needs to be consistent with the parameters in it */ private List<String> list = new ArrayList<>(); /** * Write get, set method is easy to use */ public Map<String, String> getPerson() { return person; } public void setPerson(Map<String, String> person) { = person; } public List<String> getList() { return list; } public void setList(List<String> list) { = list; } }
3. Use
@Autowired private PersonConfig personConfig; @Test public void contextLoads() { Map<String, String> person = (); List<String> list = (); ("image:"+(person).toString()); ("list:"+ (list).toString()); } //Output result image:{"sex":"man","name":"zhangsan","age":"11","url":"xxxxxxxx"} list:["apple0","apple1","apple2"]
