增加一个JasperReportConfig

package com.zns.config;

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.config.annotation.DefaultServletHandlerConfigurer;
import org.springframework.web.servlet.config.annotation.EnableWebMvc;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurerAdapter;
import org.springframework.web.servlet.view.jasperreports.JasperReportsMultiFormatView;
import org.springframework.web.servlet.view.jasperreports.JasperReportsViewResolver;

@Configuration
@EnableWebMvc
public class JasperReportConfig extends WebMvcConfigurerAdapter {

    @Override
    public void configureDefaultServletHandling(DefaultServletHandlerConfigurer configurer) {
        configurer.enable();
    }

    @Bean
    public JasperReportsViewResolver getJasperReportsViewResolver(){
        JasperReportsViewResolver resolver = new JasperReportsViewResolver();
        resolver.setPrefix("classpath:jasperreport/"); //src/main/resources/jasperreport，将jrxml放入该目录
        resolver.setSuffix(".jrxml");
        resolver.setReportDataKey("datasource");
        resolver.setViewClass(JasperReportsMultiFormatView.class);
        resolver.setOrder(0);
        return resolver;
    }
}

 

 

控制器部分代码

public List<Product> getProductList() {
    List<Product> list = new ArrayList<>();
    for (int i = 1; i <= 20; i++) {
        list.add(new Product(String.valueOf(i), "名称" + i));
    }
    return list;
}

@RequestMapping(path = "/pdfPreview", method = RequestMethod.GET)
public ModelAndView pdfPreview(final ModelMap modelMap) {
    JRDataSource dataSource = new JRBeanCollectionDataSource(getProductList());
    modelMap.put("format", "pdf");
    modelMap.put("datasource", dataSource);
    modelMap.put("Parameter1", "hello 你好");
    return new ModelAndView("test", modelMap);
}
