Spring Boot アノテーションはモックデータを実装します

1. 注意事項

package com.jayce.boot.route.component.mock;

import io.swagger.annotations.ApiModelProperty;

import java.lang.annotation.*;

@Documented
@Target(ElementType.METHOD)
@Retention(RetentionPolicy.RUNTIME)
public @interface MockData {

    @ApiModelProperty("模拟值key")
    String key() default "";
}

2. セクション

package com.jayce.boot.route.component.mock;

import com.jayce.boot.route.common.util.SpringUtil;
import lombok.extern.slf4j.Slf4j;
import org.aspectj.lang.ProceedingJoinPoint;
import org.aspectj.lang.Signature;
import org.aspectj.lang.annotation.Around;
import org.aspectj.lang.annotation.Aspect;
import org.aspectj.lang.annotation.Pointcut;
import org.aspectj.lang.reflect.MethodSignature;
import org.springframework.stereotype.Component;

import java.lang.reflect.Method;

@Slf4j
@Aspect
@Component
public class MockAspect {
    @Pointcut("@annotation(com.jayce.boot.route.component.mock.MockData)")
    public void pointCut() {
    }

    @Around("pointCut()")
    public Object around(ProceedingJoinPoint joinPoint) throws NoSuchMethodException {
        //用的最多通知的签名
        Signature signature = joinPoint.getSignature();
        MethodSignature msg=(MethodSignature) signature;
        Object target = joinPoint.getTarget();
        //获取注解标注的方法
        Method method = target.getClass().getMethod(msg.getName(), msg.getParameterTypes());
        //通过方法获取注解
        MockData mockData = method.getAnnotation(MockData.class);
        String key = mockData.key();
        MockService mockService = SpringUtil.getBean(MockService.class);
        Object mockValue = mockService.getMockValue(key);

        return mockValue;
    }
}

3. アナログデータクラス

package com.jayce.boot.route.component.mock;

import com.github.pagehelper.PageInfo;
import com.google.common.collect.Lists;
import com.jayce.boot.route.common.util.PageUtil;
import com.jayce.boot.route.entity.LibraryBook;
import org.springframework.stereotype.Service;

import java.util.HashMap;
import java.util.List;
import java.util.Map;

@Service
public class MockService {
    /**
     * 获取mock数据
     *
     * @param key key
     * @return java.lang.String
     */
    public Object getMockValue(String key) {
        Map<String, Object> map = new HashMap<>();
        map.put("key1", "{1,2,3}");

        PageInfo<LibraryBook> testPage = new PageInfo<>();
        List<LibraryBook> list = Lists.newArrayList(LibraryBook.builder()
                .bookId(1L)
                .bookName("HerryPoter")
                .build());
        testPage = PageUtil.build(list, 10, 1, 10);
        map.put("testPage", testPage);

        return map.get(key);
    }
}
