找不到能够从类型 [java.lang.String] 转换为类型 [java.util.LinkedHashMap<java.lang.String, java.lang.String>] 的转换器

Question

spring boot 2.1.1 无法读取 yml 配置到 LinkedHashMap

这是我的班级

我提供了 get 和 set 函数。但它不起作用。

@Getter
@Setter
@Configuration
@ConfigurationProperties("shiro")
public class ShiroConfiguration {
    private LinkedHashMap<String, String> filterChainDefinitions;
}

这是我的配置

shiro:
  filterChainDefinitions:
    /**: origin

这是错误信息

Description:

Failed to bind properties under 'shiro.filter-chain-definitions' to java.util.LinkedHashMap<java.lang.String, java.lang.String>:

    Reason: No converter found capable of converting from type [java.lang.String] to type [java.util.LinkedHashMap<java.lang.String, java.lang.String>]

Action:

Update your application's configuration

Answer 1

您可以使用配置属性。前任

@Component
@EnableConfigurationProperties
@ConfigurationProperties(prefix = "shiro")
class YourComponent {

    private HashMap<String, Integer> filterChainDefinitions;

    public HashMap<String, Integer> getFilterChainDefinitionsta() {
        return filterChainDefinitions;
    }

    public void setFilterChainDefinitions(HashMap<String, Integer> filterChainDefinitions) {
        this.filterChainDefinitions= filterChainDefinitions;
    }

}
