Spring使用@Value注解各种类型的值

在application.properties写入下面代码

test.boolean=true test.string=abc test.integer=123 test.long=123 test.float=1.2345678123456 test.double=1.2345678123456 test.array=1,3,4,5,6,1,2,3 test.list=1,3,4,5,6,1,2,3 test.set=1,3,4,5,6,1,2,3 test.map={name:"张三", age:18}

使用junit进行测试

@RunWith(SpringRunner.class) @SpringBootTest(classes = {ApplicationBootstrap.class}) public class DemoTest { @Value("${test.boolean}") private Boolean testBoolean; @Value("${test.string}") private String testString; @Value("${test.integer}") private Integer testInteger; @Value("${test.long}") private Long testLong; @Value("${test.float}") private Float testFloat; @Value("${test.double}") private Double testDouble; @Value("#{'${test.array}'.split(',')}") private String[] testArray; @Value("#{'${test.list}'.split(',')}") private List<String> testList; @Value("#{'${test.set}'.split(',')}") private Set<String> testSet; @Value("#{${test.map}}") private Map<String, Object> testMap; }
