配置文件
server.port=8084 server.servlet.context-path=/springboot # 中文乱码 server.servlet.encoding.force-response=true server.servlet.encoding.force=true server.servlet.encoding.charset=UTF-8 server.servlet.encoding.enabled=true server.tomcat.uri-encoding=UTF-8 # 排除 #spring.devtools.restart.exclude=static/**,public/** # 使用springboot 4.2之前配置顺序 spring.config.use-legacy-processing=true # person对象 person.id=1 person.name=Jack person.hobby=打篮球 person.family=father,mother person.map.k1=v1 person.map.k2=v2 person.pet.type=dag person.pet.name=??
测试:
package com.qkjia.springboot_01_demo;
import com.qkjia.pojo.Person;
import org.junit.jupiter.api.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.test.context.junit4.SpringRunner;
@RunWith(SpringRunner.class) // 测试启动器,并加载Spring Boot测试注解
@SpringBootTest // 标记为Spring Boot单元测试类,并加载项目的ApplicationContext上下文环境
class Springboot01DemoApplicationTests {
// 配置测试
@Autowired
private Person person;
@Test
void contextLoads() {
System.out.println(person);
}
}
咋回事:
好了 :
这个
server.servlet.encoding.force-response=true server.servlet.encoding.force=true server.servlet.encoding.charset=UTF-8 server.servlet.encoding.enabled=true server.tomcat.uri-encoding=UTF-8
加
来了一遍
