pom.xml文件中加入spring-boot-configuration-processor依赖

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-configuration-processor</artifactId>
    <optional>true</optional>
</dependency>

idea启用enable annotation processing

编写了正确的属性配置类

package com.pzy.component.webstarter.support.configuration;

import org.springframework.boot.context.properties.ConfigurationProperties;

/**
 * @author pzy
 * @date 2018/11/18
 */
@ConfigurationProperties(prefix = "component.web", ignoreInvalidFields = true)
public class WebStarterProperties {

    private GlobalExceptionProperties globalException;

    public GlobalExceptionProperties getGlobalException() {
        return globalException;
    }

    public void setGlobalException(GlobalExceptionProperties globalException) {
        this.globalException = globalException;
    }
}

项目pom文件,编译插件配置 (重点)

<!-- Compiler 插件, 设定 JDK 版本 -->
            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-compiler-plugin</artifactId>

                    <showWarnings>true</showWarnings>
